Re: how to add hwdb of keyboard

[Stefan Huchler]

I build a package for it:

(define-module (x220-hwdb)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (gnu packages compression)
  #:use-module (guix build-system copy)
  #:use-module (guix licenses))

(define-public x220-hwdb
  (package
   (name "x220-hwdb")
   (version "1.0")
   (source (origin
            (method url-fetch)
            (uri 
"https://github.com/spiderbit/emacs-ergo-thinkpad-kb-layout/archive/master.zip";)
            (sha256
             (base32
              "0rx791b7mq5visa9ckyf7py4lz5ml51hn4mzz4rmlpnlrcds4x8v"))))
   (build-system copy-build-system)
   (inputs `(("unzip" ,unzip)))
   (synopsis "Bla")
   (description "Bla bla bla")
   (home-page "https://www.gnu.org/blablabla";)
   (license gpl3+)))

and tried to link it to the expected location:

(service special-files-service-type
                  `(("/etc/udev/hwdb.d/90-X220-keyboard.hwdb"
                     ,(file-append x220-hwdb "90-X220-keyboard.hwdb"))))

the problem is that the hwdb is compiled but read only, so the file must
basically be there before the eudev package builds this db.

Is there a better way doing this?
