Return as a file-like object a generic initrd, with kernel modules taken from LINUX. FILE-SYSTEMS is a list of file-systems to be mounted by the initrd, possibly in addition to the root file system specified on the kernel command line via 'root'. MAPPED-DEVICES is a list of device mappings to realize before FILE-SYSTEMS are mounted.

When true, KEYBOARD-LAYOUT is a <keyboard-layout> record denoting the desired console keyboard layout. This is done before MAPPED-DEVICES are set up and before FILE-SYSTEMS are mounted such that, should the user need to enter a passphrase or use the REPL, this happens using the intended keyboard layout.

QEMU-NETWORKING? and VOLATILE-ROOT? behaves as in raw-initrd.

The initrd is automatically populated with all the kernel modules necessary for FILE-SYSTEMS and for the given options. Additional kernel modules can be listed in LINUX-MODULES. They will be added to the initrd, and loaded at boot time in the order in which they appear.

Return the list of statically-linked, stripped packages to check FILE-SYSTEMS.

Return as a file-like object a Linux initrd (a gzipped cpio archive) containing GUILE and that evaluates EXP, a G-expression, upon booting. All the derivations referenced by EXP are automatically copied to the initrd.

Return the list of Linux modules needed to mount FILE-SYSTEMS.

Return a file-like object that contains a list of locale name/encoding pairs such as ("oc_FR.UTF-8" . "UTF-8"). Each pair corresponds to a locale supported by GLIBC.

Return a locale directory containing all of LOCALES for each libc package listed in LIBCS.

It is useful to list more than one libc when willing to support already-installed packages built against a different libc since the locale data format changes between libc versions.

Return a <locale-definition> corresponding to NAME, guessing the charset, or #f on failure.

Raise an error if DEVICE needs modules beyond LINUX-MODULES to operate. DEVICE must be a "/dev" file name.
