Thanks for the report!  I can reproduce this by formatting a btrfs 
image file and loop-mounting it to /tmp.

This looks like an upstream bug to me.  Do you have time to file 
one?  We're using the <https://github.com/lsof-org/lsof> upstream 
since Victor Abell retired.

Alternatively we could disable this test in Guix ‘for now’ with a 
comment--but we both know how long it will remain unfixed.

Side note: I tried to implement upstream's test workflow[0] but 
got new failures (i.e. we're not running all the tests yet).  I 
haven't tried fixing those yet.

Kind regards,

T G-R
