A usually-trustworthy poster tells us that the method most likely to
work without bugs involves dump/restore instead of tar/pax/cpio/afio
(though people use them).
I'm guessing you'd want to do the following somewhere with lots of room,
where "X" is the filesystem mount point.
dump -0u -B716800 -f 1,2,3,4,5,6,7,8,9 X
Repeat for each filesystem, using different filenames.
You should be able to burn those files directly to the CD as long as the
filesizes are multiples of 2K (maybe "-b 2" would help), without using
"mkisosfs". (I've done so with "afio" archives.)
For small filesystems, you could use "mkisofs" to combine some archives.
Note that I haven't done this myself yet, so check the man pages first.
Someone with a low CD budget might write a script which does this:
-- on each specified fs, run dump | gzip >file
-- pack files (using "split" and "mv") into CD-sized directories and
run mkisofs on them.
-- prompt the user for CD, burn it, repeat
