This rework allows to use an (efi-bootloader-chain) like this, which is able
to boot over network or local storage, depending on whether the bootloader
target has support for symbolic links:
(operating-system
(bootloader
(bootloader-configuration
(bootloader
(efi-bootloader-chain
grub-efi-netboot-removable-bootloader
#:packages (list my-firmware-package
my-u-boot-package)
#:files (list (plain-file "config.txt"
"kernel=u-boot.bin"))
#:hooks my-special-bootloader-profile-manipulator))
(targets '("/booti/efi"))
…))
…)
* doc/guix.texi (Bootloader Configuration): Describe the new
‘grub-efi-netboot-removable-bootloader’. Mention the file names used and that
the UEFI Boot Manager is not modified. Advise to disable write-access over
TFTP.
* gnu/bootloader.scm (efi-bootloader-profile): Allow a list of packages and
collect everything directly in the profile, avoiding a separate collection
directory. Renamed the profile from "bootloader-profile" to
"efi-bootloader-profile".
[bootloader-collection]: Rename to...
[efi-bootloader-profile-hook]: ... this and remove unused modules. Do not
create the now extraneous collection directory.
(efi-bootloader-chain): Add PACKAGES and DISK-IMAGE-INSTALLER arguments.
Remove handling of the collection directory, now only calling the given
installer procedure.
* gnu/bootloader/grub.scm (make-grub-efi-netboot-installer): New helper.
(make-grub-configuration): New helper based on (grub-configuration-file). Add
a GRUB argument, fix indentation, remove previous code retrieving GRUB from
CONFIG.
(grub-configuration-file): Make use of make-grub-configuration.
(grub-efi-configuration-file): New procedure.
(grub-cfg): New variable to replace "/boot/grub/grub.cfg".
(install-grub-efi-netboot): Remove, splitting logic to...
(make-grub-efi-netboot-installer): ... this new helper procedure, as well as
to make-grub-efi-netboot, added below.
(grub-bootloader): Adjust to use the GRUB-CFG.
(grub-efi-bootloader): Likewise. Removed inheritance and declare all fields
explicitly.
(make-grub-efi-netboot-bootloader): New procedure.
(grub-efi-netboot-bootloader): Use it.
(grub-efi-netboot-removable-bootloader): New variable.
* gnu/packages/bootloaders.scm (make-grub-efi-netboot): New procedure.
