Parameters

uuid (string) – boot device UUID

Returns

kernel boot arguments

Return type

str

get_boot_path(target='disk')[source]

Bootloader lookup path on boot device

If the bootloader reads the data it needs to boot, it does that from the configured boot device. Depending if that device is an extra boot partition or the root partition or or based on a non standard filesystem like a btrfs snapshot, the path name varies

Parameters

target (string) – target name: disk|iso

Returns

path name

Return type

str

get_boot_theme()[source]

Bootloader Theme name

Returns

theme name

Return type

str

get_boot_timeout_seconds()[source]

Bootloader timeout in seconds

If no timeout is specified the default timeout applies

Returns

timeout seconds

Return type

int

get_continue_on_timeout()[source]

Check if the boot should continue after boot timeout or not

Returns

True or False

Return type

bool

get_gfxmode(target)[source]

Graphics mode according to bootloader target

Bootloaders which support a graphics mode can be configured to run graphics in a specific resolution and colors. There is no standard for this setup which causes kiwi to create a mapping from the kernel vesa mode number to the corresponding bootloader graphics mode setup

Parameters

target (string) – bootloader name

Returns

boot graphics mode

Return type

str

get_install_image_boot_default(loader=None)[source]

Provide the default boot menu entry identifier for install images

The install image can be configured to provide more than one boot menu entry. Menu entries configured are:

  • [0] Boot From Hard Disk

  • [1] Install

  • [2] Failsafe Install

The installboot attribute controlls which of these are used by default. If not specified the boot from hard disk entry will be the default. Depending on the specified loader type either an entry number or name will be returned.

Parameters

loader (string) – bootloader name

Returns

menu name or id

Return type

str

get_menu_entry_install_title()[source]

Prefixed menu entry title for install images

If no displayname is specified in the image description, the menu title is constructed from the image name

Returns

title text

Return type

str

get_menu_entry_title(plain=False)[source]

Prefixed menu entry title

If no displayname is specified in the image description, the menu title is constructed from the image name and build type

Parameters

plain (bool) – indicate to add built type into title text

Returns

title text

Return type

str

name (string) – title name

Returns

quoted text

Return type

str

setup_disk_boot_images(boot_uuid, lookup_path=None)[source]

Create bootloader images for disk boot

Some bootloaders requires to build a boot image the bootloader can load from a specific offset address or from a standardized path on a filesystem.
