or just the subsequent boot).
- * bootctl and kernel-install will now read KERNEL_INSTALL_MACHINE_ID
- and KERNEL_INSTALL_LAYOUT from kernel/install.conf. The first
- variable specifies the machine-id to use for installation. It would
- previously be used if set in the environment, and now it'll also be
- read automatically from the config file. The second variable is new.
- When set, it specifies the layout to use for installation directories
- on the boot partition, so that tools don't need to guess it based on
- the already-existing directories. The only value that is defined
- natively is "bls", corresponding to the layout specified in
