I've just installed a CD writer and am trying to use it for backups
but have encountered a problem that I don't understand. On an
essentially stock Red Hat 6.1 (Intel) installation, with all updates,
and using the mkisofs-cdrecord-1.8a40-4rh6.1 rpm from
ftp.falsehope.com, if I tell mkisofs to include /usr/src/linux-2.2.12,
it gets everything in that directory hierarchy. But if I ask for
/usr/src, the iso9660 file system has a directory
/usr/src/linux-2.2.12 but nothing below that point, at least as far as
I can tell by mounting it on the loopback device. I've tried this
from the command line and using the gcombust front-end, with various
combinations of flags, with the same results.
It doesn't seem to be a question of the directory depth, since I could
create a test file system with depth of at least 10 and see all the
files at each level.
I don't know very much about the ISO9660 standard and its extensions,
or mkisofs, so I'm pretty much at a loss here. I'd be grateful for
suggestions, pointers to the relevant documentation, etc. (I'd also
be interested in suggestions about ways to use CDs for backups. I
realize that it might go faster and use fewer CDs to write, say,
bzipped tar files for backups, with the tradeoff of not being able to
get at the files directly by mounting a CD.)
Thanks,
George Avrunin
