Thanks for the suggestion.  Let me see if I understand how this would 
work.  Correct me if you had something else in mind.

1. When creating the various texlive-collection-* packages, instead of 
creating postinstall scripts, I would drop files into 
/usr/share/texmf-dist/postinstall containing the postinstall information.

2. There would be a new package, say _texlive-postinstall, which would 
take care of the postinstall tasks, with arguments lumped together when 
possible.  I guess the various files in 
/usr/share/texmf-dist/postinstall would have to be renamed (with the 
addition of ".done"?) afterwards.

Did I get that right?

P.S. One detail: I don't think running fmtutil-sys --refresh is 
sufficient.  Wouldn't you also have to run fmtutil-sys --missing to 
create format files for the first time?
