     6 # I've no idea if it's complete. But at least it worked for me.

     7 #

     8 # Before using it, you have to prepare your DVD(-RAM):

     9 # to be a pseudo tape for amanda: It needs a file system and

    10 # a "data" directory.

    11 #

    12 # 1) create a file system

    13 #    e.g. mkudffs --vid=<LABEL> --media-type=dvdram --utf8 <DEVICE>

    14 # 2) mount <DEVICE> <MOUNTPOINT>

    15 # 3) mkdir <MOUNTPOINT>/data

    16 # 4) umount

    17 #

    18 # ## amanda.conf:

    19 # changerdev=<your dvd-ram>

    20 # tapedev=file:<mountpoint>

    21 #

    22 # ## sudoers.conf

    23 # backup  ALL = (root) NOPASSWD: /bin/mount, /bin/umount, /usr/bin/eject

    24 #

    25 # ## and the above mentioned commands
