To get /dev/dvd, add the following to /etc/devfs.conf: link cd0 dvd This will add a symlink to /dev/dvd whenever /dev/cd0 is present at boot time. You may also want to add: perm cd0 0666 perm pass0 0666 to allow general user access to the DVD for both reading and writing. You can use devfs.rules to set the permissions to a drive connected after boot, but devfs.rules lacks the ability to create the symlink. You can create it with 'ln -s', though, if you have root access. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
