I've had this error as well. Rock ridge encodes long file names to 8.3
names, for ISO9660 compatibility. It seems that under some
circumstances the algorithm will fail in finding unique names. The
error you get is along the lines of
mkisofs error: '/veryverylongname1 and '/veryverylongname2 have the same Rock Ridge name '_VERY000.;1'
I've run into this myself, where the two names were both very, very
long directory names which were identical in the first 100 or so
characters. The solution I found was to rename one of the directories,
but I guess that isn't always an option.
I suspect, though I cannot prove, that this is a bug in mkisofs rather
than a genuine limitation of Rock Ridge. Unless you have so many names
in one directory that all the 8.3 filenames are taken it should be
able to handle this. I have not been able to reproduce the error -- I
guess I should have kept a note of the directory names. Perhaps you
(the OP) can reproduce it if you still have the troublesome
directories you were trying to back up?
