I'm not Yaakov, but, may I throw in a dumb idea?

What if fontconfig installs scripts for sh and csh in /etc/profile.d,
which has only one task:  It checks if the fc cache is older than the
modification date of the Windows fonts directory.  If so, it either
calls fc-cache or, if that takes too long, it simply informs the user
in distinct words that fc-cache needs running.

Would that work?  Does it make sense?
