Yes, that's exactly what I meant: it makes little sense to make sure
that setup.exe does the right thing (it should not hang of course),
when after user login running latex still doesn't work.

Indeed, I don't want to go that way.

Because I do not like to make the wrong fix.  In this case, it will
probably hurt very few people, so it would make sense to think a bit
and do it correctly, if possible.

See, I can easily add unsetting bunch of variables to post-texmf.mf, eg

   unset MFINPUTS TEXINPUTS TEXMF TEXMFCNF TFMFONTS VARTEXFONTS

but it makes little sense unless I also do that in a profile.d script
(ugh).

Then, just pick a variable from texmf.cnf and set it to a silly value
in Windows, eg

   pool_size=2

and your tetex setup will be broken again.

Jan.
