The problem is that mktexmf is a shell script (=no suid possible) that
is started with the rights of the user. So the former solution required
all users that wanted to use TeX to have write access below
/var/cache/fonts. In addition for buildds the default now-questions-
asked installation had to have directories below /var/cache/fonts with
world write access. We had a system to restrict these rights to some
group, but the debconf question and code were quite complicated and
confused many users.
