Method Details

[hide private]

is_valid_stage1_device(self, device)

source code

Return True if the device is a valid stage1 target device.

Also collect lists of errors and warnings.

The criteria for being a valid stage1 target device vary from platform to platform. On some platforms a disk with an msdos disklabel is a valid stage1 target, while some platforms require a special device. Some examples of these special devices are EFI system partitions on EFI machines, PReP boot partitions on iSeries, and Apple bootstrap partitions on Mac.

Overrides: BootLoader.is_valid_stage1_device: (inherited documentation)

grub_device_name(self, device)

source code

Return a grub-friendly representation of device.

Disks and partitions use the (hdX,Y) notation, while lvm and md devices just use their names.

Overrides: GRUB.grub_device_name

write_config_console(self, config)

source code

Write console-related configuration.

Overrides: BootLoader.write_config_console: (inherited documentation)

write_device_map(self)

source code

Write out a device map containing all supported devices.

Overrides: GRUB.write_device_map

_encrypt_password(self)

source code

Make sure self.encrypted_password is set up properly.

Overrides: GRUB._encrypt_password

write_config(self)

source code

Write bootloader configuration to disk.

Overrides: BootLoader.write_config: (inherited documentation)

install(self)

source code

Overrides: BootLoader.install
