Actually, what I wanted was to be able to be able to put ext3 in the
fstab, and have mount fall back to ext2 if the kernel doesn't support
ext3.   One could imagine doing similar things with VFAT/FAT, etc.  

You responded that you didn't want to put this kind of filesystem
specific code in mount.  So that's why I suggested having mount exec
/sbin/mount.ext3, in which case I could provide the code which does
the automatic fallback.  

I agree that having this kind of fallback is somewhat ugly, but having
mount (or some program which mount execs) do this fallback is cleaner
than running a sed script over /etc/fstab.  From a usaubility point of
view, this kind of functionality really is important.  The only
question is where and how do we implement it.
