Hi. I recently wrote package definition for Linux with Reiser4 patch.

(define (linux-nonfree-urls version)
  "Return a list of URLs for Linux-Nonfree VERSION."
  (list (string-append
         "https://www.kernel.org/pub/linux/kernel/v4.x/"
         "linux-" version ".tar.xz")))


(define-public linux-reiser4
  (let* ((version "4.11.11"))
    (package
      (inherit linux-libre)
      (name "linux-reiser4")
      (version version)
      (source (origin
                (method url-fetch)
                (uri (linux-nonfree-urls version))
                (sha256
                 (base32
                  "1dvs1r3vq15akyv0yxvim6j09pqac5dagqbchvdlsw5yi4fnylc8"))
                (patches (list (computed-file "reiser4-for-4.11.0.patch"
                                              (let ((compressed (origin
(method url-fetch)

(uri "
https://downloads.sourceforge.net/project/reiser4/reiser4-for-linux-4.x/reiser4-for-4.11.0.patch.gz
")

(sha256 (base32 "1qc421bqassrxv7z5pzsnwsf9d5pz0azm96rykxh02xlrf8ig3hc")))))
                                                #~(system
                                                   (string-append
#+(file-append gzip "/bin/gunzip")
                                                                  " < "
#$compressed
                                                                  " > "

      (synopsis "Linux with Reiser4 patch.")

Can I install GuixSD on Reiser4 with it? Will it work? Does GRUB or EFI
loader in GuixSD repository supports Reiser4? Is mentioning reiser4 in
config.scm enought?

 (file-systems (cons* (file-system
                       (device "root")
                       (title 'label)
                       (mount-point "/")
                       (type "reiser4")
                       (dependencies mapped-devices))
                      %base-file-systems))

Hi Dmitry,

> Hi. I recently wrote package definition for Linux with Reiser4 patch.

Please do not post recipes for building the non-free Linux on the Guix
project’s communication channels.

The Reiser patches probably apply just as well to the Linux libre
sources.

That’s likely not enough.  You may also need to tell the initrd to
include the required modules.  This can be done by adding a field like
this to your configuration:

--8<---------------cut here---------------start------------->8---
(define %linux-modules
  '("name-of-the-module.ko"
    …))

(operating-system
  …
  (initrd (lambda (fs . args)
            (apply base-initrd fs
                   #:extra-modules %linux-modules
                   args)))
                   …)
--8<---------------cut here---------------end--------------->8---

I’m not sure if this alone would be sufficient, though.  I’m not very
familiar with this.
