How to get ptys (devfs) inside jail for FreeBSD 5.2?

[Hari Bhaskaran]

Hi,

What do I use instead of MAKEDEV (for jail) in FreeBSD 5.2?
I am getting "openpty: No such file or directory"
in the sshd's auth.log and "Server refused to allocate pty"
in the ssh client when I try to ssh-in to the jail.

So far the only response I have seen on the net is by
Clement Laforet who suggests mounting 
mount_devfs devfs ${JAIL_ROOT}/dev
See: http://lists.freebsd.org/pipermail/freebsd-questions/2003-August/014836.html

Is this secure? Is there any other way?
Any help is appreciated
