Kezdek besokalni. Ez a leírás sem pontatlan, nem működik a mount.

ns1# mount -a
mount: /usr/jails/jail1/s: No such file or directory
ns1# file /usr/jails/jail1/s
/usr/jails/jail1/s: cannot open `/usr/jails/jail1/s' (No such file or directory)
ns1# umount /usr/jails/template
ns1# umount /usr/jails/template
ns1# umount /usr/jails/template
ns1# umount /usr/jails/template
umount: /usr/jails/template: not a file system root directory
ns1# file /usr/jails/jail1/s
/usr/jails/jail1/s: directory

Valami ötlet?
