Hi everyone,

The font maps generated during profile creation (procedure
texlive-font-maps in guix/profiles.scm) are not reproducible: the order
in which the files are listed in the ls-R file is not deterministic.

As a consequence, files generated from profiles, such as Docker or
Singularity containers, are not reproducible.

I suspect that the culprit is the mktexlsr utility which generates the
non-deterministic ls-R files. It's worth exploring if it can be patched.

Cheers,
  Konrad.

Unfortunately, I think there are other parts not reproducible in TeX
Live (e.g., formats).

There is a sort option in the "mktexlsr" executable. It doesn't seem to
be accessible from the command line, tho. My Perl-fu is too weak to know
how to proceed from there.
