Yes, over the full content of the texlive distribution.

Okay, why not; I used "share" because normally the subdirectories end up in 
"share".

This would be an opportunity to ask him a few questions, so why not.

Or we could leave it empty in some way; just call it "free"? It is clear 
that we will only package free software; so a license field that can only 
state "a collection of free licenses, for details, see the source" conveys 
really no information at all. So I do not see what to construct here. My 
suggestion:

(define fsf
  (license "fsf"
           "http://www.gnu.org/licenses/"
           "A collection of free licenses according to the FSF, see the 
source for details."))

After looking at it, my impression is that at least the build process 
should be much easier (once the right order of installation determined).

There is one edition per year, commonly refered to as "TeX Live 20YY"; so 
there is no reason to go into more datails.

Very elegant, thanks for the suggestion! But actually, this manual symlink 
phase has become superfluous by some directoty related configure flags I 
just added.

Okay. Here it is less useful, since "unpack" changes directories, so a 
"chdir ".."" will remain in any case.
