bug#48519: texlive-bin cannot be installed in a profile

[raid5atemyhomework via Bug reports for GNU Guix]

In recent commits, `texlive-bin` cannot be installed in a profile.  This can be replicated by doing:

    guix pull
    guix install texlive-bin

Or with a specific recent commit:

    guix time-machine --commit=b7c7a61 -- install -p tmp texlive-bin

Note that it fails at the "building Tex Live configuration" phase; `guix build texlive-bin` builds perfectly fine, it is the installing of the package into *any* profile which fails.


However, in a previous commit a few weeks ago, `texlive-bin` *could* be installed into a profile:

    guix time-machine --commit=131265e -- install -p tmp texlive-bin # Succeeds



So, doing a `git bisect` between those two commits, I got to this commit:

```git
commit a6b8794c69446730b5f12eb8eefc5ef3b99c97dc
Author: Ricardo Wurmus <rekado@elephly.net>
Date:   Mon May 3 15:34:46 2021 +0200

    profiles: texlive-configuration: Refresh font maps.

    * guix/profiles.scm (texlive-configuration): Run updmap to generate font maps
    necessary for pdflatex and other tools.

 guix/profiles.scm | 51 ++++++++++++++++++++++++++++++++++++++++++++++++---
 1 file changed, 48 insertions(+), 3 deletions(-)
```

Its direct parent can install `texlive-bin` perfectly fine:

    guix time-machine --commit=eb930be -- install -p tmp texlive-bin # Succeeds

The above commit fails:

    guix time-machine --commit=a6b8794 -- install -p tmp texlive-bin # Fails


The specific error when constructing the profile is this:

```
updmap: open() failed: No such file or directory at /gnu/store/jy61rq7jhiqwjcmm4agr2hpk3f7ggnks-texlive-bin-20190410/bin/updmap line 2153.

        You can disable non-existent map entries using the option
          --syncwithtrees.

I don't know how to debug this further, unfortunately.


***Is*** this an issue?  It seems I can just remove `texlive-bin` and still have `pdflatex` and co working on my profile.

Yes.  The problem is that the texlive-configuration profile hook 
is hooked to texlive-bin instead of texlive-base (which includes 
texlive-bin).  I’ve been meaning to change that but haven’t gotten 
around to doing this.

This should be fixed with commit 
bd8e7621b880c529cc69102bd6817d79257526ee.

Only the presence of “texlive-base” triggers the profile hook now. 
This is acceptable because any TeX Live subset will need to 
include “texlive-base”.
