It's as much a limitation of the ISO9660 format, where the maximum size of a file fragment is 2 GB. Some OSs handle fragmented files on ISOs, some do not. >So, >what I did was to break up the large files into smaller chunks.

There is, if compatibility is not an issue. Actually, what I do is dump or tar directly to a DVD. I set the "tape size" in each program to the size of a DVD, as blocks in the appropriate blocksize. So I'm making DVDs with no filesystem. I believe that this is /more/ future-proof, as, in the future, rather than getting a working then-old-style filesystem working and a then-old-style restore or tar working, I only have to do the latter. I write the DVDs with "growisofs -dvd-compat -Z /dev/dvd=/tmp/dvd". -- ____________________________________________________________________ TonyN.:' The Great Writ <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' is no more. <http://www.georgeanelson.com/>
