A word of warning for people doing 'fmtutil --all' on texlive upgrade

It seems from this thread http://bbs.archlinux.org/viewtopic.php?id=78778 that some people do 'fmtutil --all' as user after they upgrade texlive.

-> all of you will need to do this on *every* major texlive upgrade!

-> noone (especially not pacman) can't do this for you (because of the way texlive works)!

Some more blabbering about the issue:
- the way texlive works is that if it finds some files locally ("in the user's tree"), it simply ignores their analogues in the system folders.
- this implies for instance that if you ever generate the formats as a user ('fmtutil --all' as a user), tex will *always* use those, although on upgrade pacman automatically regenerates the system-wide formats.
- also if you ever change some font or language settings locally, you might get some trouble on upgrade due to the fact that the local settings (which are being used) don't match the version of texlive installed.

How to check things:
- 'kpsewhich <filename>' tells you which of the various files named <filename> the tex system "sees"
- all the local changes are saved ~/.texlive/texmf-config or ~/.texlive/texmf-var. So deleting the ~/.texlive directory will reset any local changes.
