Subject: bug#54003: local-file after Guile update
Date: Mon, 14 Feb 2022 21:50:08 +0000

Hi,

I have the following dotfiles directory structure where I store my Guix home
config:

|-etc
|
|-subdir
|   |
|   |-home


I often use the 'local-file' procedure in modules in the home directory. For
example in /subdir/home/shells.scm:

#+begin_src scheme :scheme guile :season guile
(simple-service 'add-zsh-files
                home-files-service-type
                `(("config/zsh/zshrc"
                   ,(local-file "../../etc/zsh/zshrc"))))
#+end_src
And it works, as expected.

The following example also worked before the
076e825dc5d585943ce820a279fffe4af09757fb (gnu: guile: Add version 3.0.8 as
'guile-3.0-latest') commit.

in /subdir/home/wm.scm: 
#+begin_src scheme :scheme guile :season guile
(service
 home-rofi-service-type
 (home-rofi-configuration
  (config-rasi
   `(,#~(format
         #f "@theme \"~a\""
         #$(local-file "../../etc/rofi/nord.rasi"))))))
#+end_src

After 076e825dc5d585943ce820a279fffe4af09757fb
using (local-file "../../etc/rofi/nord.rasi") and not
(local-file "etc/rofi/nord.rasi") causes an error:

guix home: error: canonicalize-path: No such file or
directory: "../../etc/rofi/nord.rasi".

The example that causes the error uses the original Guix home implementation,
which uses gexps.  When I figure out how to make a minimal reproducer that
does not depend on it, I will update this report.
