Hello,It would be helpfull to see what the error message is.
I have some jails running on ZFS, so I have to mount devfs's into them.
For this purpose, I have some similar lines in /etc/fstab:
devfs /pool/jail/ldap/dev devfs rw 0 0
Where /pool is a ZFS filesystem.
This has worked until today -when I upgraded from a previous 7-STABLE
(FreeBSD 7.0-STABLE #16: Fri Mar 7 14:30:08 CET 2008) to today's STABLE-
but not anymore.
The boot process fails with something like WARNING: $true wasn't set, see
man rc.conf (or something similar, I don't have the exact error message, but
I can reproduce if it's needed), and the problem is that the rc scripts try
to mount the devfs (and nullfs) stuff to the yet unmounted ZFS, so
/pool/jail/ldap/dev doesn't exist.
For "jails" you don't need to place any devfs entries into /etc/fstab.
The /etc/rc.d/jail script will automatically mount/umount the devfs
for you. Just add the following to /etc/rc.conf:
jail_<jailname>_devfs_enable="YES"
jail_<jailname>_devfs_ruleset="MyJailRule" <- this is optional
You can also do the same thing with "chroot", an example script is
/etc/rc.d/named.
