Creating your own Calculate Linux ISO
With Calculate Builder, you can create your custom ISO image based on any Calculate flavour, providing the software and the settings you need.
Go to the directory where the ISO you need is located and display available files:
# cd /var/calculate/linux # ls cld-15.17-x86_64.iso
Assembly preparation
# cl-builder-prepare --iso cld-15.17-x86_64.iso Подготовить новую сборку * Исходный образ: Calculate Linux Desktop KDE 15.17 x86_64 20160519 * Профиль системы: distros:CLD/amd64 * Местонахождение сборки: /var/calculate/builder/distros_CLD_amd64 * Идентификатор сборки: distros:CLD/amd64 * Использовать слои для сборки: да * Свободное место на диске: 12.5G Запустить процесс? (Yes/No): yes * Распаковка образа системы ... [ ok ] * Подключение ресурсов ... [ ok ] * Настройка сборки ... [ ok ] * Сборка подготовлена успешно
Update to the current state
# cl-builder-update -f
Set up your assembly
Chrooting
chroot is an operation for changing the root directory in Unix-like operating systems. A program running in chroot will only have access to the files contained in the chroot directory.
# chroot /run/calculate/mount/distros_CLD_amd64
Deleting applications
Imagine that you want to remove Firefox from your system:
# emerge -C firefox
Installing software without intervention
Now install the Qupzilla web browser:
# emerge -av qupzilla
...and InkScape, a free and open-source vector graphics editor:
# emerge -av inkscape
... WINE, free software that allows users of UNIX-like systems to run applications that were created for Microsoft Windows:
# emerge -av wine
..and Thunderbird to manage your emails:
# emerge -av thunderbird
Installing software with intervention
Installing some applications may require manual intervention from the user.
Install, for example, an Owncloud front-end for cloud storage, synchronization and data exchange.
# emerge -av net-misc/owncloud-client ... The following keyword changes are necessary to proceed: (see "package.accept_keywords" in the portage(5) man page for more details) required by net-misc/owncloud-client (argument) ---- =net-misc/owncloud-client-2.2.4 ~amd64 ---- Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT). Carefully examine the list of proposed changes, ying special attention to mask or keyword changes that may expose experimental or unstable packages.
As you can see from the message about, you need to edit /etc/portage/package.keywords/custom.
Add the necessary string by typing the following in the command line:
# echo "=net-misc/owncloud-client-2.2.4 ~amd64" >> /etc/portage/package.keywords/custom
Warning: To add a parameter, be sure to type two >> symbols!
Now, if you restart, the installation process will go ahead without any further modification.
Quit the chroot environment.

Custom ISO target directory
The resulting system image will be stored in the /var/calculate/linux/.
The name of the ISO file will include the build date.
Break the assembly process
Warning: Do not exit if you intend to make changes to your build later.
# cl-builder-break
Access to a previously created build
Warning: After rebooting, you cannot access the build you created earlier. You need to reconnect manually.
To do this, go to the image directory and run the following command:
# cl-builder-restore
Own profile in an ISO
If you want to have your settings when booting from an image over PXE, you can configure the system you are working in in the same way and copy the /home/guest directory into the prepared build at /var/calculate/builder/distros-CLD-amd64 before actually completing the build.
Warning: These settings will not be used when installing the system. To apply your settings to the system you install from a custom image, you need to edit the templates.
