I am... disturbed... that fss attaches to a mounted filesystem rather
than to the underlying block device.  If it did the latter, it would be
easy to arrange for TRT to happen in /etc/rc.d/*, no?  Since it doesn't,
it looks to me like magic parsing of fstab would be required; ugh.  You
are right about this.
