Configuration Common Linux

This page details a common configuration for Linux, independent of the underlying platform.

To Do

• Basic configuration for standard installation
• Move settings that can be recovered from HOME directory in separate section.

Base

On Debian, login as root and add default user (uid 1000) as root.

su -
USERNAME=$(awk -F: '/:1000:/ {print $1}'
gpasswd -a $USERNAME /etc/passwd) sudo

# Terminate all users process !!! this will FORCE LOGOUT !!!
# ... alternatively: su - $USERNAME to avoid logout
loginctl terminate-user $USERNAME

Install etckeeper (with git).

# ### etckeeper + git

sudo apt install git etckeeper
git config --global user.email "user@server.com"       # Make sure this is defined for admin user + root
git config --global user.name "User Name"              # or release upgrade might fail in the future
sudo su -
git config --global user.email "user@server.com"
git config --global user.name "User Name (root)"
logout

sudo vi /etc/etckeeper/etckeeper.conf                  # Select git, AVOID_DAILY_AUTOCOMMITS, AVOID_COMMIT_BEFORE_INSTALL
sudo etckeeper init
sudo etckeeper commit "1st commit"
cd /etc
sudo vi .gitignore                                     # Ignore resolv.c* (and cups/subscriptions.* before Ubuntu Precise)
sudo git rm --cached resolv.c*
sudo git rm --cached cups/subscriptions.*              # No longer needed on Ubuntu Precise and after
sudo etckeeper commit "ignore resolv.c*, cups/subscriptions.*"

Then we install ssh, ssh server, and vim + mc.

sudo apt install ssh vim mc                            # Debian 9+
sudo apt install ssh vim-gnome mc                      # Older

From now, the configuration can continue either locally or remotely (using ssh).

We now install a few repositories, as required.

• See also Ubuntu Tweak, XBMC, Gnome Terminator, Medibuntu (replaced by Videolan)

sudo vi /etc/apt/sources.list                          # Debian: enable 'main non-free contrib'
                                                       # Ubuntu: enable 'partner' and 'extra' (if available)
sudo add-apt-repository ppa:phoerious/keepassxc        # Ubuntu: keepassxc
# sudo add-apt-repository ppa:synapse-core/ppa         # Ubuntu <14.04 - Synapse
sudo add-apt-repository ppa:tualatrix/next             # Ubuntu: Ubuntu Tweak
sudo add-apt-repository ppa:team-xbmc/ppa              # Optional: XBMC

sudo etckeeper commit "Update repositories"
sudo apt update

• hosts — Update /etc/hosts

sudo vi /etc/hosts                                                 # Add any relevant entries.
                                                                   # Make sure localhost has FQDN:
                                                                   #     127.0.1.1	myhost.domain.com
sudo etckeeper commit "update hosts file"

• sudoers — Create new files in /etc/sudoers.d as required:

# envkeep
# http_proxy, https_proxy -- to keep proxy settings for apt-get etc
# GREP_OPTIONS            -- keep grep options
# DISPLAY, XAUTHORITY     -- avoid doing 'xhost local:root' before launching X pgm
# HOME                    -- e.g. to keep git aliases and settings when using etckeeper
# PASSWD                  -- e.g. to pass password via env. var to <code>mount.cifs</code>
echo "Defaults env_keep += \"http_proxy https_proxy GREP_OPTIONS DISPLAY XAUTHORITY HOME\"" | sudo tee /etc/sudoers.d/envkeep
# Truecrypt
echo "ALL ALL = NOPASSWD: /usr/bin/truecrypt" | sudo tee /etc/sudoers.d/truecrypt
# Privoxy - no longer needed with tun2socks-manager
#echo "ALL ALL = (ALL) NOPASSWD: /etc/privoxy/set-network-config" | sudo tee /etc/sudoers.d/privoxy
# rfkill - no more used
#echo "ALL ALL = NOPASSWD: /sbin/rfkill" | sudo tee /etc/sudoers.d/rfkill
sudo chmod o-r /etc/sudoers.d/*
sudo etckeeper commit "update sudoers.d files"

• Restore home profile (from git)

# Restore my profile
mv home/.git .
rm -rf home
git reset --hard
git st
export PATH=$PATH:$HOME/bin
set-network.sh
~/setup.sh

• Restore old keyboard dead keys behaviour by uninstalling im-config:

DOES NOT WORK - on Bullseye, still get the strange behaviour. Maybe due to Wayland?

sudo apt remove im-config       # DOES NOT WORK - To avoid ¨ / ^ displaying while composing, and other nasty side effects

Locale (at least since Debian 10 Buster)

• ATTENTION Using the locale en_DK.UTF-8 break Wine Command Prompt (bad keyboard config).

To fix that, for instance for PlayOnLinux, edit file /usr/share/applications/PlayOnLinux.desktop

vi /usr/share/applications/PlayOnLinux.desktop

-Exec=playonlinux %F
+Exec=env LC_ALL=en_US.UTF-8 playonlinux %F

• Edit /etc/locale.gen, and uncomment line en_DK.UTF-8 UTF-8, then update the locale

sudo vi /etc/locale.gen
# ...
sudo locale-gen

• Edit /etc/default/locale, and add line LC_TIME="en_DK.UTF-8" [1], [2]

sudo vi /etc/default/locale
# ...

• In Gnome, select en_DK.UTF-8 for format in Region and Language settings.

Kernel update

• Install latest kernel [3]

# Get Utopic kernel
sudo apt install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic
# Get Vivid kernel
# DO NOT UPDATE TO VIVID X.ORG - IT LEAKS LIKE HELL
# sudo apt install --install-recommends linux-generic-lts-vivid xserver-xorg-lts-vivid libgl1-mesa-glx-lts-vivid libegl1-mesa-drivers-lts-vivid
sudo apt install --install-recommends linux-generic-lts-vivid

Desktop - Gnome

Disable Wayland

Wayland is improving, but still some hickups with the following applications:

• Synapse (constant pop up inhibiting shortcuts), and global shortcut not working (but we could set up a gnome shortcut Ctrl-Alt-Space with synapse as command).

To disable:

• At startup screen, select the user.
• Click settings icon in bottom right corner, and select "Gnome on X.Org"
• Login with the user and logout.

Gnome extensions

To install Gnome extensions on Debian:

• There are gnome-shell-extension* package, but installing these has no effect.
• To install extension, go to Chromium. If necessary, in Chromium, install the add-on Gnome Shell Integration (go to https://chrome.google.com/webstore/).
• Gnome extensions can be configured through the Gnome Tweaks (package gnome-tweaks).

AlternateTab

• By default, Gnome Alt-Tab will group windows from the same application. To get rid of this annoying behaviour and restore the good old one, install extension AlternateTab.
• Debian: To install it, go to Gnome Tweaks (package gnome-tweaks).
• Ubuntu: press Super key, then AlternateTab, it will be installed automatically. This might require installing sudo apt install gnome-tweak-tool [4].

system-monitor (github)

• This replaces applet indicator-multiload that no longer works since Ubuntu Bionic.
• Requires the following package:

sudo apt install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0  gir1.2-clutter-1.0   # Ubuntu
sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0  gir1.2-clutter-1.0               # Debian

• However the indicator conflicts with owncloud client indicator (no longer visible).
• Selects memory, cpu, network.

No title bar

• Revive Unity-like merging of window title bar with desktop top bar.
• Caveat: Window's menu is not merged [5]
• Gnome 3.38: we have to use fork from kendling/no-title-bar to fix for No JS Module 'tweener' found in search path.

Gnome Global Application Menu

• AVOID 'ALT' KEY STEALING FOCUS → In extension configuration (via Gnome Tweaks), Go to main menu, click on Alt, then Backspace to remove the shortcut. Breathe again.
• To merge application menu in top title bar.
• As a side-effect, this extension fixes the owncloud-icon-not-showing bug.

Custom Corner

• Top left corner: Gnome default (default).
• Top right corner: Show overview.

Gnome theme

We install a Mac OS theme.

Enable Gnome User Themes

• Open Gnome tweaks, and enable extensions User themes (this enable theme selection for Shell' in Appearance).

Mojave light theme

• Guide on OMG buntu.
• Download and install McMojave:

sudo apt install gtk2-engines-murrine gtk2-engines-pixbuf
sudo apt install libglib2.0-dev-bin                             # Needed to install gdm theme
git clone https://github.com/vinceliuice/Mojave-gtk-theme.git
cd Mojave-gtk-theme
./install
sudo ./install -g

• In Gnome tweaks → Appearance → Applications, select Mojave-light.
• In Gnome tweaks → Appearance → Shell, select Mojave-light.

La Capitaine Icon Pack

• Download and install:

mkdir -p ~/.icons
cd ~/.icons
git clone https://github.com/keeferrourke/la-capitaine-icon-theme.git

• In Gnome tweaks → Appearance →, select La-capitaine-icon-theme.

Fonts

• In Gnome Tweaks → Fonts, select the following fonts:
  • Interface Text: Lucide Sans Regular 11 (was Cantarell Regular 11).
  • Document Text: Lucida Sans Regular 11 (was Sans Regular 11)
  • Monospace Text: Fantasque Sans Mono Regular 11 (was Monospace Regular 11)
  • Legacy Window Titles: Lucida Sans Unicode Bold 11 (was Canterell Bold 11)

Launcher

• We stick to Synapse with Ctrl-Alt-Space, but this requires running X.Org (fuzzy mode in Albert is just broken).

Other options

• Noobslab MacBuntu 18.04 guide.

Gnome tweak

• Top bar → Application Menu → OFF.

Gnome Mouse

• When playing games, flat acceleration is recommended.
• On Debian 10 with BT mouse, speed -0.2 gives best result.

gsettings reset-recursively org.gnome.desktop.peripherals.mouse
gsettings set org.gnome.desktop.peripherals.mouse accel-profile flat
gsettings set org.gnome.desktop.peripherals.mouse speed -0.2
dconf dump /org/gnome/desktop/peripherals/mouse/
# [/]
# speed=-0.20000000000000001
# accel-profile='flat'

Miscellaneous Gnome

• Disable emoji shortcut Ctrl-Shift-E (interfere with Terminator).

• Launch ibus-setup, and delete the shortcut for emoji.

Development packages

• Install packages - development

sudo apt install gitk git-gui git-doc exuberant-ctags cscope ruby meld colordiff  # ruby for Vim plugin snipMate.vim

# Optional
sudo apt install gitweb git-svn

Optional packages

AutoFS

sudo apt install autofs

• Mount mnemosyne shares as NFS autofs (see [6]) and as SMB autofs

Enabled/created the following automounters in /etc/auto.master:

/net                /etc/auto.net                   --ghost
/smb/mnemosyne      /etc/auto.smb.mnemosyne         --ghost
/smb/lacie-cloudbox /etc/auto.smb.lacie-cloudbox    --ghost

• Create configuration file /etc/auto.smb.mnemosyne
• Create SMB credential files /etc/auto.smb.mnemosyne.* (see man mount.cifs)
• Created path for mount points:

sudo mkdir /net
sudo mkdir -p /smb/mnemosyne
# ls /net/mnemosyne
# sudo mkdir -p /mnt/mnemosyne
# for i in /net/mnemosyne/volume1/*; do sudo ln -s $i /mnt/mnemosyne/$(basename $i); done

• Or recover settings from an already configured host:

scp griffin:tmp/autofs.tgz .                                        # Configure autofs
sudo tar -xvzf autofs.tgz
sudo cp etc/* /etc

• If necessary, mount shares read-only: add option ro in /etc/autofs.smb.mnemosyne
• Create a writable share in /etc/fstab:

//mystique/local /mnt/mystique/local   cifs    noauto,vers=1.0,_netdev,noperm,iocharset=utf8,sec=ntlm,username=superwoman   0       0

Firefox

sudo apt install firefox

• Set Ctrl-Tab to show last tab. Browse to about:config, and set browser.ctrlTab.previews to True.

fzf

fzf is a very fast fuzzy-finder written in Go.

It is installed when installing vim plugins. To install it in bash:

git clone https://github.com/junegunn/fzf.git ~/.fzf    # Skip this step if already present
cd ~/.fzf
./install

Gpg

sudo apt install gnupg-agent pgpgpg

• Added use-agent at end of ~/.gnupg/gpg.conf
• Edit ~/.gnupg/gpg.conf as necessary.

KeePass

sudo apt install keepassxc            # Now using KeepassXC
# sudo apt install keepassx

We store the database on Owncloud, and sync to local git repository with cron.

Script private/kdbx/sync_from_owncloud.sh:

#! /bin/bash

BASEDIR=$(dirname "$(readlink -nf "${BASH_SOURCE[0]}")")
cd "$BASEDIR"

KDBX=work.kdbx
OWNCLOUD_DIR=~/ownCloud/kdbx

if ! diff -q $OWNCLOUD_DIR/$KDBX $KDBX; then
    echo "Adding $KDBX to git..."
    cp $OWNCLOUD_DIR/$KDBX $KDBX
    git add $KDBX
    git commit -m "Sync keepassx db with Owncloud"
fi

Cronjob:

31 * * * *      chronic ~peetersm/private/kdbx/sync_from_owncloud.sh

Workaround

• Set kbd layout to fix autotype bug ([7]). Create ~/.xprofile and /etc/skel/.xprofile [8]:

#!/bin/sh

#
setxkbmap be

LibreOffice

Install latest LibreOffice by adding the PPA:

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt update

mDNS

sudo apt install libnss-mdns avahi-daemon mdns-scan

• To scan:

mdns-scan

Machine should broadcast its ip address on griffin.local to all avahi clients. For some strange reason, avahi may append a -2 suffix to broadcast name. To avoid that, edit /etc/avahi/avahi-daemon.conf and set host-name variable:

host-name=griffin

In some cases, avahi may detect host name conflicts on the network where there isn't.

Oct 24 19:32:06 zavcxl0006 avahi-daemon[810747]: Host name conflict, retrying with griffin-2

One fix for that is to restrict the set of interfaces (here only wired and wifi) [9], [10]:

allow-interfaces=enp0s31f6, wlp1s0

There is yet another potential conflict with systemd-resolved [11], [12]:

Oct 24 19:41:28 zavcxl0006 avahi-daemon[811344]: *** WARNING: Detected another IPv4 mDNS stack running on this host.

Midnight Commander

sudo apt instal mc

• See reference page.
• Use vi as standard viewer/editor.
• Installed version from mc official repository to fix file highlighting issue.

neovim / vim

sudo apt install neovim
sudo pip3 install neovim-remote   # nvr, needed by Vimtex

See Neovim page for up-to-date install instructions.

Neovim / vim plugins are installed via vim-plug, which is part of the home git repository.

Set Neovim as alternatives for vim/viewer (useful for Midnight Commander).

sudo update-alternatives --config vim        # Select 'nvim'
sudo update-alternatives --config view       # Select 'view.nvim'

However the following plugins require extra configuration:

YouCompleteMe

This is the install script to enable the minimum features. Note that this is done automatically by vim-plug.

cd ~/.vim/plugged/YouCompleteMe
./install.py --clang-completer

cpsm

Run this script after installing the plugin with vim-plug.

sudo apt install libboost-all-dev cmake python-dev libicu-dev
cd ~/.vim/plugged/cpsm
./install.sh

NFS

• NFS Server (nfs-kernel-server nfs-common rpcbind)||See NFS for more details; Created entries in /etc/exports. rpcbind replaces portmap since Oneiric.

Samba

sudo apt install smbclient cifs-utils

• Use package smbfs for u1204 Precise Pangolin and before

SSH

• Create / restore private key:

ln -sf ../private/ssh/id_rsa_work ~/.ssh/id_rsa

• If using bin/ssh-agent-refresh.sh:

Terminator

sudo apt install terminator

• Install the new terminator that depends on GTK3 (terminator-gtk3, version 1.97~ppa3).
• On latest Debian, install patch for middle click on Wayland (Terminator).
• See Terminator.
• See Gnome Terminator for tips.
• Set background to transparent 6% (through ~/.config/terminator/config)
• Set scrollback to infinite scrollback
• Custom geometry terminator --geometry=1220x720+100+100 (in application menu)
• Font Lucida Console, 9 (on nxl67002ux / nxl67063ux), or Bitstream Vera Sans Mono Roman 9 (on nxl67063 Cygwin-X).
• (not needed on trusty) Set terminator as default terminal for Ctrl-Alt-T [13]:

gsettings set org.gnome.desktop.default-applications.terminal exec 'terminator --geometry=1220x720+100+100'

• On Debian, with Gnome, add new shortcut for Ctrl-Alt-T:

dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/binding' '<Primary><Alt>t'
dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/command' '/usr/bin/terminator'
dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/name' 'Terminal'

Thunderbird

See Thunderbird.

tmux

• Alternative to screen, but with support for multiple panes like terminator

Make sure that tmux is at least version 2.2. If not install it:

• Compile 2.2-3 package from yakkety. See Package Management for instruction.
• Compile from sources.

VirtualBox

sudo apt install virtualbox

Debian Buster

• Mouse pad scrolling issue, and micro-freeze issues with vbox 6.04+ coming from distribution. As workaround we use Oracle (testing) packge (and ext-pack):

sudo apt remove virtualbox
sudo ./VirtualBox-6.0.5-129923-Linux_amd64.run

Wine

• Wine (wine)||See Wine page

XBMC

• see XBMC

Configuration

• Install fonts

• Fantasque Sans Mono

mkdir ~/.fonts
wget https://github.com/belluzj/fantasque-sans/releases/download/v1.7.1/FantasqueSansMono.tar.gz
tar xvzf FantasqueSansMono.tar.gz -C ~/.fonts/ --wildcards *.ttf
sudo fc-cache -fv

• Apply common settings (see below)
• Applications not from repositories:
  • Panda glGo 1.4.1 (local page, does not work on Oneiric 64-bit)
• Install latest updates:

sudo apt dist-upgrade

• Restore scrollbar behaviour in GTK3 [14], [15].

Use Shift+Click or Template:Right click to get the jump to click behaviour.

MIME

Use Chromium for SVG files:

# when using 'see'
echo 'image/svg+xml; /usr/bin/chromium %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap
echo 'image/svg+xml-compressed; /usr/bin/chromium %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap

# when using 'xdg-open' or midnight commander:
xdg-mime default chromium.desktop image/svg+xml

Use Zathura for PDF files:

# when using 'see'
echo 'application/pdf; /usr/bin/zathura %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap

# when using 'xdg-open' or midnight commander:
# -- was "org.gnome.Evince.desktop"
xdg-mime default org.pwmt.zathura.desktop application/pdf

Debian

Add contrib non-free repositories to apt source [16].

Add sid release apt sources.

cat << EOF | sudo tee /etc/apt/sources.list.d/sid.list
# Unstable / Sid
deb http://ftp.debian.org/debian/ sid main contrib
deb-src http://ftp.debian.org/debian/ sid main contrib

Install these packages

sudo apt install mlocate dnsmasq-base
sudo apt install libcanberra-gtk-module      # Fix truecrypt warning

We install Firefox 56 and Thunderbird 52.8 to preserve some important add-ons. These packages and their dependencies are no longer available but they can still be downloaded on http://snapshot.debian.org/:

sudo dpkg -i firefox_56.0-2_amd64.deb \
    libcurl3_7.52.1-5+deb9u9_amd64.deb \
    libevent-2.0-5_2.0.21-stable-3_amd64.deb \
    libhunspell-1.3-0_1.3.4-2_amd64.deb \
    libhunspell-1.6-0_1.6.2-2_amd64.deb \
    libvpx4_1.6.1-3+deb9u1_amd64.deb \
    thunderbird_52.8.0-1~deb8u1_amd64.deb
sudo apt install -f
echo "firefox hold" | sudo dpkg --set-selections
echo "thunderbird hold" | sudo dpkg --set-selections

Nvidia

See Debian wiki. Mainly:

• Make sure the system is up-to-date (nvidia module will be compiled against kernel headers, which may fail if headers are no longer available).

sudo apt udpate
sudo apt dist-upgrade

• Run nvidia-detect:

sudo apt install nvidia-detect
sudo nvidia-detect
# ...
# It is recommended to install the
#     nvidia-legacy-340xx-driver
# package.

• Install the reported driver (eg. here nvidia-legacy-340xx-driver)

sudo apt install linux-headers-$(uname -r|sed 's/[^-]*-[^-]*-//') nvidia-legacy-340xx-driver

• Run nvidia-xconfig to create a new xorg.conf file (!! This fails on Optimus systems. See wiki !!).

sudo apt install nvidia-xconfig
sudo nvidia-xconfig

• Reboot

sudo reboot

More issues

• Apparently driver nouveau gets loaded as well. Let's blacklist it:

echo blacklist nouveau | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf

• Boot error: nvidia-persistenced[557]: Failed to open libnvidia-cfg.so.1: libnvidia-cfg.so.1: cannot open shared object file: No such file or directory.

• We uninstall some packages:

sudo apt remove nvidia-persistenced libnvidia-cfg1:amd64 libgl1-nvidia-tesla-440-glvnd-glx:amd64 libglx-nvidia-tesla-440-0:amd64 libnvidia-tesla-440-glcore:amd64 nvidia-tesla-440-alternative

Workaround

• Install custom udisks package, version 1.0.4-5ubuntu2.1fuu1, to fix unreadable DVD-RW. See udisks, or bug 635499).

sudo dpkg -i udisks_1.0.4-5ubuntu2.1fuu1_amd64.deb

• Add the following to ~/.bash_profile and ~/.profile to Meta-key (Alt) not working and Midnight Commander displays Press any key... after each command when in tmux session [17]:

# This fix meta-key support and stop mc displaying "Press any key..." in tmux session
if [ $TERM = "screen" ]; then
    export TERM=xterm
fi
if [ -n "$TMUX" ]; then
    export COLORTERM=rxvt
fi

The pit (things to tidy up)

Miscellaneous

• Optional - Fix flash issue

# Optional - Fix blue video in flash (see below for details)
sudo mkdir /etc/adobe
echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null
sudo etckeeper commit "Fix blue video bug in adobe flashplayer"

• Install packages - optional

# Optional applications
sudo apt install gnugo qgo uligo cgoban quarry pgpgpg powertop

Synapse

sudo apt install synapse

Install with:

sudo add-apt-repository ppa:synapse-core/ppa
sudo apt-get update && sudo apt-get install synapse

• Start synapse → Preferences → click Startup on login
• Still in preferences, set Activate shortcut to Ctrl-Alt-Space
• If Synapse does not show up on keypress, there is maybe a racing condition.

• Create a file /usr/bin/synapse-delayed:

#! /bin/bash
sleep 3 && exec synapse --startup

• Do chmod a+x /usr/bin/synapse-delayed.
• Edit synapse.desktop file (there is both if startup application was already set), and set Exec=/usr/bin/synapse-delayed.

Opera

sudo apt install opera

See Opera to fix apt key issues.

Flash

• Flash Plugin 10 (flashplugin-installer)||
• Enable Ubuntu partner repository if needed(deb http://archive.canonical.com/ubuntu lucid partner).
• In case of error failure to download extra data files flashplugin-installer, try

sudo apt-get --reinstall install flashplugin-installer

(Old recipe:

sudo aptitude autoremove "flashplugin-*"
sudo aptitude install flashplugin-installer

)

• broken— This is too unstable, see next solution — On Ubuntu 12.04 with NVidia card, there is a bug Flash video appears blue. That link recommends to update libvdpau1, but in my case it was already at the latest version. Instead the following did the trick (from bug 968647):

sudo mkdir /etc/adobe
echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null

• Another solution is to disable hardware acceleration, by going into flash player settings. If the settings window is not clickable, first disable unity 3D (for instance with metacity --replace&)
