how does this work?
i couldn't see anything in the manual about this.

well, i suppose if rc were modified to support open read-write,
mount <>{command} /mnt/xxx
would look slightly more logical (and reflect what's actually happening).

that's true.
but it's also nice to see the mount points actually named in the
script that sets them up, i think. (i always have to look in the manual
page to see whether it's  (e.g.) /n/tapefs or /mnt/tapefs...)

don't they have to do that currently anyway?
