Ok, this makes sense. Can this happen for other formats, too? I guess
one of the things that confused me was the hardcoded 'latex' where
build_format_if_format_exists is called. And that it isn't called in the
'normal form' right now.

Ah, I understand. Looking at fmtutil --help I just found the option
--catcfg which seems still slower than your method. I am not sure if the
normaliziation and sorting applied by --catcfg is necessary here, but it
looks as if spaces are allowed before the the format name in
fmtutil.cnf. So maybe you ought to grep for something like
"^[[:space:]]*$2[[:space:]]".

Due to the magic comments this should not happen when packages are
installed or unistalled. But the local admin can always change the
config file to shoot in his own foot. I am not sure if one can (or
should) inhibit this.
