after make process and before installing he tell me this,but che directory /compat/linux/dev is created,yet so i believe he did it and i did not type any of these commands:

mkdir -m 0755 -p <Jail root dir>/dev
rm -f <Jail root dir>/compat/linux/dev/null
mknod <Jail root dir>/compat/linux/dev/null c 2 2
chmod 666 <Jail root dir>/compat/linux/dev/null

...but
( if i type mkdnod </usr/sbin/jail ...ecc it tell me: 
mknod: node must be type 'b' or 'c'
and if i type the mkdir <...ecc it tell me:
dev: is a directory )

SO
