I want to backup to DVD so I can upgrade to 5.3. dump in 4.10 does not have a -P option, and growisofs says nothing about handling spanning, so how do I span my dump over multiple DVDs? dump -h0 -B 4589840 -S /usr says I'm going to need 6.18 "tapes". I'm going to crack open a beer and just pipe it, to see what happens. Then some day if all goes well I will split /usr into /usr and /usr/home, 'cause this is ridiculous.
