Can Not Install Font Packages

[Igor Pechtchanski]

Harold,

There are mounts, and there are mounts.  If the user creates her own mount
for the fonts directory, it's her responsibility to remove the mount after
uninstalling.  However, the only purpose of this particular mount created
by the postinstall package is to force binmode for the fonts directory.
I don't see anything wrong with removing this mount before the files
themselves are removed (especially since it's going to be re-created later
by the postinstall script).

You're right that in this particular case the preremove scripts would not
have been run, so there's no point in targeting it.  I believe in cleaning
up after postinstall scripts, though, and preremove scripts are the right
place to do it.  FWIW, my quick-and-dirty idea was basically to have each
font package postinstall script create a uniquely named file in a known
location, and each preremove script remove its corresponding file and then
check whether any other files exist, and if not, umount.

I think for setup to detect when a mount is stale would be a good idea
anyway.  Currently, AFAIK, setup doesn't have a notion of "failing to
install a package" with subsequent reinstall, but if it ever does, this
would be the right way to handle the situation.
