2024-01-14bootloader: grub: Add support for loading an additional initrd....In order to be able to provide decryption keys for the LUKS device, they need to be available in the initial ram disk. However they cannot be stored inside the usual initrd, since it is stored in the store and being a world-readable (as files in the store are) is not a desired property for a initrd containing decryption keys. This commit adds an option to load additional initrd during the boot, one that is not stored inside the store and therefore can contain secrets. Since only grub supports encrypted /boot, only grub is modified to use the extra-initrd. There is no use case for the other bootloaders. * doc/guix.texi (Bootloader Configuration): Describe the new extra-initrd field. * gnu/bootloader.scm (<bootloader-configuration>): Add extra-initrd field. * gnu/bootloader/grub.scm (make-grub-configuration): Use the extra-initrd field.

2023-07-13bootloader: grub: Use rumpdisk-style root when booting with "noide"....* gnu/bootloader/grub.scm (make-grub-configuration): When "noide" is in arguments, use device name "wd0" rather than "hd0". Signed-off-by: Josselin Poiret <dev@jpoiret.xyz> Janneke Nieuwenhuizen

2022-12-01gnu: bootloader: Rework chaining, add grub-efi-netboot-removable-bootloader....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.

2022-06-06bootloader: grub: Add removable grub-efi bootloader option....For single-disk installs (external USBs) and for amnesiac UEFIs, Guix is not found using its default Grub EFI bootloader location of /boot/efi/EFI/Guix/grubx64.efi means the Guix install will not be found. To handle this, we can place the bootloader file in the UEFI specification location, overwriting any other OS that may have placed a file there. This location is namely /boot/efi/EFI/BOOT/BOOTX64.efi. Grub has explicit support for this location/situation with the `--removable` flag. * gnu/bootloader/grub.scm (install-grub-efi-removable) (grub-efi-removable-bootloader): New variables. * doc/guix.texi (Bootloader Configuration): Document it.
