External configurations

The "ExternalConfigs" keyword will tell kickstarter to look for additional YAML files to parse. Lists will be merged in order of inclusion, ie, if there is a key/value pair, the latest YAML file to be included (or the one having ExternalConfigs and that key), will specify the final value corresponding to the key. When lists are merged, later yaml file contents always will be first in the list, earlier ones appended.

"ExternalConfigs" should be accompanied with a list of directories.

Example:

  ExternalConfigs:
   - /usr/share/kickstarts/mer-core
   - /usr/share/kickstarts/n900-hard

Declarations

There are two types of objects in a kickstarter file, one is declarations and one is configurations.

Declarations are sets of descriptions which has a name. These cannot inherit from each other.

Configurations are what is actually getting made into kickstart files, has to have a name and a filename.

Example:

   Foo:
      Kernel: kernel-foobar

   Configurations:
        - Name: Mer Core for foobar
          FileName: mer-core-foobar
          Inherits:
            -  Foo
          Groups: 
            - Mer Core

Configurations

The "Configurations" keyword is a list, specifies which kickstart files should be generated, see example above

Inheritance

Example:

   Inherits:
      - foo
      - bar

This keyword can be used within configurations, to list what declarations to inherit from. This basically merges the declarations together, latter ones being prioritized over earlier, when merging lists, latter entries is earlier in the list than entries from earlier declarations.

Language

This keyword specifies the default locale used in the resulting image.

Example:

 - Language: en_US.UTF-8

Keyboard

This keyword specifies the default keyboard layout used in the resulting image.

Example:

  - Keyboard: us

Timezone

This keyword specifies the default timezone used in the resulting image.

Example:

  - Timezone: UTC

or

  - Timezone: Europe/Copenhagen

Partition setup - Part vs PartSize + FileSystem

There's two ways of laying out partitions with kickstarter. One is Part, which uses a partition layout file, and PartSize and Filesystem, which uses just one root partition, on which you indicate size and filesystem type.

Part

Partition layout is in order, first partition is first partition.

Layout:

  part [MOUNTPOINT] --size=SIZE_IN_MB --ondisk LIKELYDISKNAME --fstype=FSTYPE [--active]

mountpoint is where it gets mounted, likelydiskname is the probable name of the disk when it runs in the device. Fstype is file system type (btrfs, ext4, etc..), when there, --active means that the partition is flagged as bootable

Example:

  - Part: foo/bar/part

Example of partition file:

  part / --size=1800  --ondisk mmcblk0p --fstype=btrfs

  # This is not used currently. It is here because the /boot partition
  # needs to be the partition number 3 for the u-boot usage.
  part swap --size=192 --ondisk mmcblk0p --fstype=swap

  # This partition is made so that u-boot can find the kernel
  part /boot --size=64 --ondisk mmcblk0p --fstype=vfat

PartSize and Filesystem

This method creates just one root partition, with a certain size, and a certain file system. PartSize is always in megabyte.

Example:

 - PartSize: 500
 - FileSystem: ext4
