tial 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.

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.
