Installation of cdbkup done with
./configure --with-snardir=/mnt/sbackup --with-dumpgrp=root. /mnt/sbackup is a 10 GB partition I created for use with scdbackup. It’s a staging area for burning DVDs. the dumpgrp was necessary because cdbkup used a default group of operator, that I don’t have on my system.
The autodetect feature couldn’t tell how big my DVD was, so it used the default of 650 MB. Then after the message
Collecting input data... it just exited.
