Configure Live System

Create configuration directory

As unprivileged user in the virtual machine create a config-test1 directory in your home directory.

cd
if [ ! -d config-test1 ]
then
    mkdir -p ~/config-test1
    chmod 755 ~/config-test1
else
    echo 'E: Directory config-test1 already exists!'
fi

Create build directory

As unprivileged user in the virtual machine create the livesys1 directory in your home directory.
Create the “custom” subdirectory as symbolic link to the directory created above.

cd
if [ ! -d livesys1 ]
then
    mkdir -p livesys1
    chmod 755 livesys1
else
    echo 'E: Directory livesys1 already exists!'
fi

cd
cd livesys1
ln -s /home/user/config-test1 custom

Replace /home/user by the unprivileged users home directory.
Important: Use an absolute path name.

Variables set automatically

Some variables are set automatically by the scripts and exported to sub-scripts:

LIVESYSTYPE
The live system type to produce, specified as argument to the dklivesys-build-livesys script, either “dktoolian” or “disklessian”.

DEBVMAJ
Debian major version code name, one from: “bookworm”, “bullseye”, “buster”, “stretch”, or “jessie”.
The current dklivesys version can only produce Debian Bookworm live systems on Debian Bookworm hosts.

DSRC
Data directory, derived from the scripts full path name, typically /usr/local/share/dklivesys/livesys-data or ${HOME}/Downloads/dklivesys-1.0.10/share/dklivesys/livesys-data.

The dklivesys.conf configuration file

Syntax

The custom/dklivesys.conf file can be used to configure several features of the live system.

The file consists of comment lines and key=value lines. In comment lines the first non-whitespace character is a raute character (#).

Reasonable defaults are choosen for most settings.

The file is a configuration file, not a shell file, so you can use

DESKTOP=gnome

but not

DESKTOP="gnome"

Use of double quotes (") and back ticks (`) is denied, for security reasons lines containing these characters are ignored.

Leading and trailing whitespaces are ignored both in key and value.

The following keys can be used:

General live system configuration


DESKTOP=string
Desktop to use in the live system, one from: “none” (DKtoolian only), “gnome”, or “xfce”.
The following desktops are not really supported, their use in DKtoolian and Disklessian is experimental: “mate”, “lxde”, “cinnamon”, “kde”, and “lxqt” (Debian Bookworm, Bullseye, Buster, and Stretch only).
Default: none for DKtoolian, gnome for Disklessian.


LIVETYPE=string
The live systems boot type, either “hybrid” or “nfs”.
Hybrid live systems are booted from USB drive, DVD or CD.
NFS live systems use a combination of PXE, DHCP, TFTP, and NFS to boot, NFSSERVER and NFSPATH must be specified.
Default: hybrid.

NFSSERVER=string
NFS server containing the root file system, specified by IP address (preferred) or host name.
This configuration item is required for LIVETYPE=nfs, ignored otherwise.
There is no default.

NFSPATH=string
Path to NFS share on server containing the root file system, specified as absolute path.
This configuration item is required for LIVETYPE=nfs, ignored otherwise.
There is no default.

PUBLISHER=string
Name of the person or organization creating the live system.

LIVEAPPENDCUSTOM=string
Kernel parameters to add.
Default: none.
Usable parameters:

Parameter Purpose
live-config.noautologin to avoid automatic login.
live-config.noroot to deny sudo for the user logged in automatically.

Kernel to use


SIDKERNEL=boolean
Use kernel from Debian Sid (unstable) instead of the kernel from the stable Debian release.
Default: no.

This feature was added on a users request.
I strongly recommend to stay with the default “no” to use the kernel from Debian stable.
See https://wiki.debian.org/DebianUnstable for information on Debian Sid.

See the Customization How-To how to use a *.deb kernel package.

Boot process

UEFISECURE=boolean
Add support for UEFI Secure Boot.
Default: yes.

BOOTMENUBEEP=boolean
Issue beep when boot menu is shown.
This notifies visually impaired users about “boot menu shown, you can append kernel parameters for screen readers now”.
Default: yes.

PLYMOUTHTHEME=string
Name of plymouth theme to show a splash screen or an animation during boot.
Default: “dklivesys” for Disklessian, “none” for DKtoolian.

The “dklivesys” theme is a very simple theme. Files for this theme are installed automatically by dklivesys-build-livesys if that theme is used.
For other themes there are two installation choices:

  • Install a Debian package providing the theme.
  • Place the files building up the theme in the custom/usr/share/plymouth/themes/themename directory.

Note: In “normal” boot process a plymouth theme is shown immediately after booting the selected boot menu item. In Debian live systems there is a little delay.
I suspect the delay is due to squashfs use, but I did not make tests to confirm this.

GRUB_GFXMODE=string
Configuration entry for GRUB_GFXMODE in the /etc/default/grub file.
Use something like “1920x1080” or “1920x1080x32” to specify screen width and height, optionaly the number of bits per pixel.
This option is typically used together with PLYMOUTHTHEME to configure the screen resolution required by the theme.

Internationalization and Localization

LANGFULL=string
Full language specification (optionally including region and/or encoding) for language to use in live system including language, region, and encoding.
Default: The systems default language automatically detected by command:

grep "^LANG=" /etc/default/locale | cut -f 2 -d '"'

LANGREG=string
Language and region specification for language to use in live system.
Default: The systems default language and region automatically detected by command:

echo $LANGFULL | cut -f 1 -d .

LANGSHORT=string
Pure language specification for language to use in live system.
Default: The systems default language automatically detected by command:

echo $LANGFULL | cut -f 1 -d . | cut -f 1 -d _

Keyboard options.
Default: none

XKBBACKSPACE=string
Backspace key, one from: “bs”, “del”, or “guess”.
Default: guess.

Networking

SHORTIFNAMES=boolean
Use short interface names to avoid WiFi deauthentication due to long interface names exceeding internal buffer sizes in driver modules.
Default: yes.

LIVEAPPENDIP=string
Kernel parameters to append for IP configuration, one from:

  • device:address:netmask:gateway:nameserver
    i.e. “eth0:192.0.2.42:255.255.255.0:192.0.2.1:192.0.2.50” to specify network interface, ip address of host, netmask, default gateway and DNS name server to use.
  • frommedia
    to inspect the live systems /etc/network/interfaces file.

Previous versions of the live-boot documentation listed the following choices which are not mentioned in the recent documentation:

  • dhcp
    to use the DHCP protocol.
  • bootp
    to use the BOOTP protocol.
  • rarp
    to use the RARP protocol.
  • on
    to attempt DHCP, BOOTP, and RARP.
  • none
    to disable networking.

Default: dhcp.

REPURLDKTOOLS=URL
URL used by apt to retrieve DK tools packages, trailing slash required,
i.e. “http://192.168.122.1/debian12/dktools/”.
Use “none” if DK tools are not needed and you did not (yet) prepare a repository.
This key is typically used when building a DKtoolian livesystem, not used when building a Disklessian.
Default: none

Package management options

UPDATESYSTEM=boolean
Update and upgrade system before building the live system.
Default: yes.

APTRECOMMENDS=boolean
Install recommended packages for packages in the package list too.
Default: yes.


ALLOWLIBREOFF=boolean

ALLOWNONFREE=boolean
Allow “contrib” and “non-free” software. Some components in computers (mostly WiFi chips, but some ethernet and other chips too) require firmware files to work. Some firmware files are licensed under conditions incompatible with the GPL used by the Linux kernel. For other firmware files the license conditions are simply unknown. If you configure the use of such non-free firmware files here, the resulting live system may be undistributable (you can use it for your own purposes but are not allowed to distribute it to other users).
Default: no.
Recommended value:

  • no, when producing a live system to distribute,
  • yes, when producing a live system for your own use.

Mirrors

Most likely you want to set up MIRRORBOOTSTRAP and MIRRORBINARY to point to nearby servers, at least to servers on the same continent.

Packages from Debian repositories

Default package sets

The following files contain default sets of packages to install for DEBVMAJ/LIVESYSTYPE/DESKTOP combinations.
Do not modify these files, inspect them only to see which packages are already listed. See next subsection how to add further packages.

${DSRC}/pkg-${LIVESYSTYPE}-host.txt
Packages to install on the build host before building the live system.

${DSRC}/pkg-${LIVESYSTYPE}-base.txt
Packages to install into both command line and desktop live systems.

${DSRC}/pkg-${LIVESYSTYPE}-firmware.txt
Firmware packages.

${DSRC}/pkg-${LIVESYSTYPE}-${DESKTOP}.txt
Packages for the specified desktop.

${DSRC}/pkg-${LIVESYSTYPE}-lang-base.txt
List of all language support packages for command line systems, used only if failed to find a language specific package list.

${DSRC}/pkg-${LIVESYSTYPE}-lang-desktop.txt
List of all language support packages for desktop systems, used only if failed to find a language specific package list.

Add further packages

Use the following files to customize the package sets for LIVESYSTYPE/DEBVMAJ/DESKTOP/LIVETYPE combinations:

  • custom/pkg.txt
  • custom/pkg-${LIVETYPE}.txt
  • custom/pkg-${DESKTOP}.txt
  • custom/pkg-${DESKTOP}-${LIVETYPE}.txt
  • custom/pkg-${DEBVMAJ}.txt
  • custom/pkg-${DEBVMAJ}-${LIVETYPE}.txt
  • custom/pkg-${DEBVMAJ}-${DESKTOP}.txt
  • custom/pkg-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}.txt
  • custom/pkg-${LIVESYSTYPE}.txt
  • custom/pkg-${LIVESYSTYPE}-${LIVETYPE}.txt
  • custom/pkg-${LIVESYSTYPE}-${DESKTOP}.txt
  • custom/pkg-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}.txt
  • custom/pkg-${LIVESYSTYPE}-${DEBVMAJ}.txt
  • custom/pkg-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}.txt
  • custom/pkg-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}.txt
  • custom/pkg-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}.txt

Each line contains one package name and optionally a comment separated from package name by raute character #.

Example custom/pkg-none.txt file line:

network-manager     # Network manager without GUI support

Packages available as local files

Create one or more of the following directories and place the *.deb files there:

  • custom/pkgs
  • custom/pkgs-${LIVETYPE}
  • custom/pkgs-${DESKTOP}
  • custom/pkgs-${DESKTOP}-${LIVETYPE}
  • custom/pkgs-${DEBVMAJ}
  • custom/pkgs-${DEBVMAJ}-${LIVETYPE}
  • custom/pkgs-${DEBVMAJ}-${DESKTOP}
  • custom/pkgs-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}
  • custom/pkgs-${LIVESYSTYPE}
  • custom/pkgs-${LIVESYSTYPE}-${LIVETYPE}
  • custom/pkgs-${LIVESYSTYPE}-${DESKTOP}
  • custom/pkgs-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}
  • custom/pkgs-${LIVESYSTYPE}-${DEBVMAJ}
  • custom/pkgs-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}
  • custom/pkgs-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}
  • custom/pkgs-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}

Note: Do not create empty directories!

Note: For netboot systems create the custom/pkgs-nfs directory and copy the

  • /usr/share/dklivesys-pkgs/klibc-utils_2.0.12-1_amd64.deb
  • /usr/share/dklivesys-pkgs/libklibc_2.0.12-1_amd64.deb
  • /usr/share/dklivesys-pkgs/live-boot_20230131_all.deb
  • /usr/share/dklivesys-pkgs/live-boot-initramfs-tools_20230131_all.deb

files created previously into this directory.

Add files to live system

If the custom/root directory is present, the contents of this directory is copied into the live systems root file system.
If you want a file to appear in the /usr/local/bin directory of the live system, place it in the custom/root/usr/local/bin directory.
Other directories can be used for files to inject into the live system for specific combinations of live system type, Debian version, desktop, and/or boot type.

  • custom/root
  • custom/root-${LIVETYPE}
  • custom/root-${DESKTOP}
  • custom/root-${DESKTOP}-${LIVETYPE}
  • custom/root-${DEBVMAJ}
  • custom/root-${DEBVMAJ}-${LIVETYPE}
  • custom/root-${DEBVMAJ}-${DESKTOP}
  • custom/root-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}
  • custom/root-${LIVESYSTYPE}
  • custom/root-${LIVESYSTYPE}-${LIVETYPE}
  • custom/root-${LIVESYSTYPE}-${DESKTOP}
  • custom/root-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}

Note: Do not create empty directories!

The ${DSRC}/root and ${DSRC}/root-* directories contain default files to inject. They are processed before the custom/root and custom/root-* directories.

Add files to initramfs

If the boot process stops at the

(initramfs)

prompt, errors occured.
Adding files to the initramfs (initial RAM file system) may help.
Place the files in one of the directories listed below.

  • custom/initramfs
  • custom/initramfs-${LIVETYPE}
  • custom/initramfs-${DESKTOP}
  • custom/initramfs-${DESKTOP}-${LIVETYPE}
  • custom/initramfs-${DEBVMAJ}
  • custom/initramfs-${DEBVMAJ}-${LIVETYPE}
  • custom/initramfs-${DEBVMAJ}-${DESKTOP}
  • custom/initramfs-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}
  • custom/initramfs-${LIVESYSTYPE}
  • custom/initramfs-${LIVESYSTYPE}-${LIVETYPE}
  • custom/initramfs-${LIVESYSTYPE}-${DESKTOP}
  • custom/initramfs-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}
  • custom/initramfs-${LIVESYSTYPE}-${DEBVMAJ}
  • custom/initramfs-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}
  • custom/initramfs-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}
  • custom/initramfs-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}

Note: Do not create empty directories!

Overwrite /etc files

Some configuration files in the live systems /etc directory and subdirectories are generated or overwritten automatically at boot time. To provide corrected versions for such files, place them in the /usr/share/dklivesys/etc directory of the live system, i.e. by using the custom/root/usr/share/dklivesys/etc directory.

A special hook copies the contents of the live systems /usr/share/dklivesys/etc to /etc at the end of the boot process immediately before the user login is allowed.

If — for example — your DHCP service provides incomplete information about DNS servers, you might want to place a correct resolv.conf file in the custom/root/usr/share/dklivesys/etc directory.

Scripts during boot process (boot hooks)

The scripts in the /usr/share/dklivesys/hooks directory are executed by the dklivesys-boot script after copying the contents of the /usr/share/dklivesys/etc directory to /etc.

To add your scripts to this directory, place them in one of the directories below, create the directory structure if necessary. Set permissions to make the scripts executable.

  • custom/root/usr/share/dklivesys/hooks
  • custom/root-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${DESKTOP}/usr/share/dklivesys/hooks
  • custom/root-${DESKTOP}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${DEBVMAJ}/usr/share/dklivesys/hooks
  • custom/root-${DEBVMAJ}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${DEBVMAJ}-${DESKTOP}/usr/share/dklivesys/hooks
  • custom/root-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DESKTOP}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}/usr/share/dklivesys/hooks
  • custom/root-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}/usr/share/dklivesys/hooks

Note: Do not create empty directories!

Build process hooks

Hooks are scripts executed while building the live system. The files must be executable. At the beginning of the name there should be a four digits decimal number to specify order of execution. The name must end on “.hook.chroot” for hooks to execute in the chroot stage and on “.hook.binary” for hooks to execute in the binary stage.

To add hooks, place the scripts in one of the following directories:

  • custom/hooks
  • custom/hooks-${LIVETYPE}
  • custom/hooks-${DESKTOP}
  • custom/hooks-${DESKTOP}-${LIVETYPE}
  • custom/hooks-${DEBVMAJ}
  • custom/hooks-${DEBVMAJ}-${LIVETYPE}
  • custom/hooks-${DEBVMAJ}-${DESKTOP}
  • custom/hooks-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}
  • custom/hooks-${LIVESYSTYPE}
  • custom/hooks-${LIVESYSTYPE}-${LIVETYPE}
  • custom/hooks-${LIVESYSTYPE}-${DESKTOP}
  • custom/hooks-${LIVESYSTYPE}-${DESKTOP}-${LIVETYPE}
  • custom/hooks-${LIVESYSTYPE}-${DEBVMAJ}
  • custom/hooks-${LIVESYSTYPE}-${DEBVMAJ}-${LIVETYPE}
  • custom/hooks-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}
  • custom/hooks-${LIVESYSTYPE}-${DEBVMAJ}-${DESKTOP}-${LIVETYPE}

Note: Do not create empty directories!

Depending on the configuration some of the hooks listed below are created automatically by the dklivesys scripts itself:

  • 0510-boot.hook.chroot
    adds the dklivesys.service service unit to the multiuser target.
     
  • 0520-ntp-conf.hook.chroot
    creates the /etc/ntp.conf file based on your NTPSERVER and USENTPDAEMON settings.
     
  • 0530-keyboard.hook.chroot
    creates the /etc/default/keyboard file based on your keyboard settings (XKBMODEL, XKBLAYOUT, XKBVARIANT, XKBOPTIONS, and XKBBACKSPACE).
     
  • 0540-desktop-install.hook.chroot
    installs the fontconfig package first, followed by the packages for your desktop.

    prevents cups-browsed from starting.
     
  • 0560-no-bluetooth
    prevents bluetooth daemon from starting.
     
  • 0570-wifi.hook.chroot
    creates a symbolic link from /dev/null to /etc/systemd/network/99-default.link. So the system only uses short names for network interfaces including WiFi. The normal long names are too long for some kernel modules, the result is WiFi deauthentication.
     
  • 0580-gnome.hook.chroot
    disables the start of trackers and runs “dconf update” if Gnome was selected as desktop.
     
  • 0590-lxde.hook.chroot
    disables the start of clipit if LXDE was selected as desktop.
     
  • 0600-consfont.hook.chroot

  • 0630-custom-pkgs.hook.chroot
    installs packages provided as local *.deb files in the pkgs directories.
     
  • 0640-clonezilla.hook.chroot
    modifies some of the clonezilla scripts if clonezilla is selected as package to install.
     
  • 0650-sid-kernel.hook.chroot
    installs the SID kernel if configured to do so.
     
  • 0660-firefox-privacy-prefs.hook.chroot
    configures some privacy-related preferences for firefox.
     
  • 0670-firefox-privacy-pols.hook.chroot
    configures some privacy-related policies for firefox and the bookmarks.
     
  • 0680-plymouth-theme.hook.chroot
    modifies the grub.cfg file if a plymouth theme was choosen.
     
  • 0800-remove-nvme-sata.hook.chroot
    removes the NVME and (S)ATA related kernel modules when building a Disklessian.
     
  • 0950-bootbeep.hook.binary
    modifies the boot menu to avoid the beep if BOOTMENUBEEP=no was choosen.
     
  • 0960-bootmenu.hook.binary
    modifies the boot menu and copies the boot splash image.
     
  • 0970-autologin.hook.binary
