bootx64.efi or bootaa64.efi into SUBDIR, which is usually efi/Guix or efi/boot,
|
|
|
|
|
below the directory TARGET for the system whose root is mounted at MOUNT-POINT.
|
|
|
|
|
|
|
|
|
|
MOUNT-POINT is the last argument in 'guix system init /etc/config.scm mnt/point'
|
|
|
|
|
or '/' for other 'guix system' commands.
|
|
|
|
|

TARGET is the target argument given to the bootloader-configuration in

|

|

…))
|
|

|
|
|
|
|
|
|
|
|
|
TARGET is required to be an absolute directory name, usually mounted via NFS,
|
|
|
|
|
and finally needs to be provided by a TFTP server as the TFTP root directory.
|
|
|
|
|
|
|
|
|
|
GRUB will load tftp://server/SUBDIR/grub.cfg and this file will instruct it to
|
|
|
|
|
load more files from the store like tftp://server/gnu/store/…-linux…/Image.
|
|
|
|
|
|
|
|
|
|
To make this possible two symlinks will be created. The first symlink points
|
|
|
|
|
relatively form MOUNT-POINT/TARGET/SUBDIR/grub.cfg to
|
|
|
|
|
MOUNT-POINT/boot/grub/grub.cfg, and the second symlink points relatively from
|
|
|
|
|
MOUNT-POINT/TARGET/%store-prefix to MOUNT-POINT/%store-prefix.
|
|
|
|
|
|
|
|
|
|
It is important to note that these symlinks need to be relativ, as the absolute
|
|
|
|
|
paths on the TFTP server side are unknown.
|
|
|
|
|
|
|
|
|
|
It is also important to note that both symlinks will point outside the TFTP root
|
|
|
|
|
directory and that the TARGET/%store-prefix symlink makes the whole store
|
|
|
|
|
accessible via TFTP. Possibly the TFTP server must be configured
|
|
|
|
|
to allow accesses outside its TFTP root directory. This may need to be
|
|

considered for security aspects."
