Getting back to this old thread so we may get pbuilder to work...

But umount calls fstab_find_mount and fstab_find_device, not
fstab_find.  I'd thus say that these former should apply the realpath
instead of fstab_find.  Could you try this instead of adding one
to do_umount?

Conversely, we need to realpath the entries being added to fstab,
that would probably have to be done in fs_set_mntent.  Care must be
taken that mntent is const.  The simplest way is probably to just make
a copy of the struct mntent, realpath both mnt_fsname and mnt_dir,
and keep the rest of the code as such.  I believe that should thus
fix mount along the way.
