Thanks, Julian, and I'd like to contemplate getting a few of my MFC
hacks that I'm running on 4.x, added to releng, if possible.

One of these things I've found very handy is the `mount' option
introduced in 5.x that allows one to specify with -F an alternate
to /etc/fstab to be used.

This I use for conditional mounting of devices which may or may
not be present, like external USB (to catch your interest, heh)
drives with a complicated partition layout.  I test if a known
drive is present at a certain device, and if so,
`mount -F /etc/fstab-da0' or `-da1' and so on, as part of my boot.

In order to adopt this change, I had to add to libc in 4.x as well
as butcher the `mount' code.  Does such a change stand a chance of
being added to 4.x, or are infrastructure changes required this way,
like to libc, off-limits outside my own hive of personal hackery?


(What's missing, as far as I know, that could be handy, is a
comparable option to `umount' when one wants to quickly detach a
drive with ten mounted filesystems.  I haven't looked at this idea)


(freebsd-legacy@ , anyone, for those of us too stubborn to join the
modern world, and get confused when the -stable list postings don't
make clear what release is being discussed, or want a quiet place to
mull over 2.2.x ?)


thanks
