I am running a DNS server in a jail and have setup a devfs mount in the
jail to have null and random devices.
The setup works fine, but once I log out then log back in the pty and
tty devices of my login get created in the jail. Which, of course, I
don't want to happen. To clarify, I'm not talking about "logging into
the jail", this occurs when logging on to the system. The jail is
stripped down, not anywhere close to a virtual server.
I do the following to create the jail'd devfs at startup:
mount_devfs devfs JAILDIR/dev
devfs -m JAILDER/dev rule -s 35 add hide
devfs -m JAILDIR/dev rule -s 35 add path null unhide
devfs -m JAILDIR/dev rule -s 35 add path random unhide
devfs -m JAILDIR/dev rule -s 35 applyset
This works great - I get a dev directory setup with just null and
random. But the second anyone logs into the system, whammo all the
sudden pty and tty devices appear inside the jail's /dev directory.
If anyone would care to unclueless me I would appreciate it.
Steve
