Raspberry Pi OS style image layout with MBR, vfat boot partition, and a root partition that can be ext4 or btrfs.
Declares (prefix: image):
| Variable | Description | Default | Validation | Policy |
|---|---|---|---|---|
IGconf_image_rootfs_type |
Root filesystem type. |
ext4
|
Must be one of: ext4, btrfs | immediate |
IGconf_image_boot_part_size |
Boot partition size |
100%
|
Size value with optional unit (bytes, k/K/M/G/s) or percentage | immediate |
IGconf_image_root_part_size |
Root partition size |
100%
|
Size value with optional unit (bytes, k/K/M/G/s) or percentage | immediate |
IGconf_image_assetdir |
Image specific asset directory |
${DIRECTORY}
|
Path to an existing directory | immediate |
IGconf_image_disksig |
MBR disk signature supplied as a non-zero 32-bit hexadecimal number, or 'random' |
random
|
Must match regex pattern: ^(random|0x(?!0{8})[0-9a-fA-F]{8})$ | lazy |
IGconf_image_devid_scheme |
How root and boot are referenced in /etc/fstab and on the kernel command line. by-slot: /dev/disk/by-slot symlinks. This layout's udev rule creates them for the boot-medium devices that rpi-storage-binder tags. partuuid: PARTUUID derived from the MBR disk signature, as Raspberry Pi OS tooling expects. Not available with pmap 'crypt': partition 2 holds the LUKS2 container, and the unlocked root filesystem is a device-mapper device with no PARTUUID of its own. |
by-slot
|
Must be one of: by-slot, partuuid | immediate |
IGconf_image_pmap |
Provisioning Map identifier for this image layout. All partitions will be provisioned unencrypted (clear). Root partition will be provisioned encrypted (crypt). |
clear
|
Must be one of: clear, crypt | immediate |
