Done.

Okay.

I wouldn’t know how.  Updates are done by changing the variables
%texlive-tag and %texlive-revision in (guix build-system texlive) and
then changing the package expressions.

Since the version strings on CTAN differ from the revision of the TeX
Live SVN repo I don’t see how we can make this robust.  For most
packages we use the SVN revision.  This is much larger (“44445”) than
the version string for packages on CTAN (e.g. “2.6a”).

Yes, we should package all the other TeX packages that are part of TeX
Live, including those that appear to be just supporting files (e.g. the
“generic” sub-directory).

I think we may need to enlarge “texlive-tiny” a little to make it more
useful.  I’ve only tested it with fastcap, and noticed that it misses
some bibtex files.

Anyway, the foundation is there and I don’t think it would take too much
effort to get us to “texlive-full” soon.

I’m pushing this to master in a few minutes.  Thanks for the review!
