Subject: [PATCH 3/5] grub-install: support prep environment block
|
|
|
|
The grub-install can be instructed to create environment block at end of
|
|
PReP paritition with probed device identities and properties in
|
|
variables to facilitate root device discovery. So far these variables
|
|
are defined for this purpose:
|
|
|
|
ENV_FS_UUID - The filesystem uuid for the grub root device
|
|
ENV_CRYPTO_UUID - The crytodisk uuid for the grub root device
|
|
ENV_GRUB_DIR - The path to grub prefix directory
|
|
ENV_HINT - The recommended hint string for searching root device
|
|
|
|
The size of environment block is defined in GRUB_ENVBLK_PREP_SIZE which
|
|
is 4096 bytes and can be extended in the future.
|
