we recently added a new option to mount, -o nodevmtime, primarily to
avoid gratuitous spinups of laptop disks just to update the mod time
on /dev/pms0..

Anyhow, the flag bit allocated in mount.h for MNT_NODEVMTIME, was
unfortunately already assigned to MNT_EXPUBLIC (export partition using
WebNFS).

I've just committed a revision to <sys/mount.h> which moves
MNT_NODEVTIME to a different unused bit.

This will produce a temporary incompatibility between new kernels and
old mount_ffs programs; if you're using -o nodevmtime mounts, you'll
need to build and install new includes and a new mount binary to get
nodevmtime functionality back.
