>Description:
When setting the jail_jailname_rootdir to a path that contains symlinks, the rc.d/jail script has problems mounting mount_devfs on that path, obviously. To solve the issue you have to put the absolute path to that rcvar.

In my opinion th rc.d/jail script should handle this, so I made a patch.

gandalf# /etc/rc.d/jail start ftpjail
Configuring jails:.
Starting jails:/etc/rc.d/jail: WARNING: /home/ftpjail/dev has symlink as parent - not starting jail ftpjail
