I went ahead and pushed that as

Guix,

After running ‘sudo guix pull’, some directories that guix 
assumes to be writable are not:

 $ guix pull
 Updating channel 'guix' from Git repository at 
 'https://git.savannah.gnu.org/git/guix.git'...
 guix pull: error: Git error: failed to create temporary file 
 '/home/adom/.cache/guix/pull/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq/.git/objects/pack/pack_git2_dVwpVq': 
 Permission denied
 $

Now Guix isn't doing anything wrong, per se, and that error 
message will tip off most jaded Unixbeards, but how about a:

 $ guix pull
 warning: /home/<USER>/.cache/… is not writable by the current 
 user <USER>
 hint: You might want to run ‘chown -R <USER>:<USER> /home/…’ 
 [or just delete it outright? -nckx]
 …

?

Thanks to adom` in #guix for posting that output.

Kind regards,

T G-R
