missing /dev/pts in jail

[richard bader]

Hello to all,

I've upgraded my FreeBSD-7.2 to 8.0-STABLE FreeBSD 8.0-STABLE #2: Mon 
Dec  7 11:27:05 CET 2009 with cvsup.

Now i've the following problem:

After system startup all jails are working fine and i can log into the 
jails with ssh.
- the jails are configured in rc.conf

After stopping a jail with '/etc/rc.d/jail stop jailtest' and restarting 
it with '/etc/rc.d/jail start jailtest' the jail is working but i cannot 
log in anymore.
The errormessage of the ssh is:

PTY allocation request failed on channel 0
Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.

When looking in the jail the device /dev/pts is missing:

[root at main1 ~]# ls -l /usr2/jails/jailtest/dev/
total 1

crw-rw-rw-  1 root  wheel    0,  33 Dec  8 22:13 zero

Any ideas

best regards
