Mario,
Well, yes & no. Basically, the o/s will not be able to mount your dvd at all,
until there is a working file system written on the DVD. Last week I would
have said that I don't think that just creating an iso9660 file system will
solve your problem as it would be a read-only file system, however, there was
a thread earlier this week that seemed to indicate that it was possible to
write an iso9660 file system "on the fly" with growisofs. I didn't read it in
detail so I can't say for certain. Search the archives for a message with the
title "DVD Backup Script (Was Re: [Bacula-users] DVD+/-RW as media without
bimgmanager?)" from Misty Stanely-Jones. In it she provides a script which
writes a backup to a DVD.
Alternatively, you could use DVD-RAM. All recent kernels support this type of
drive. You treat it just like a hard drive, which is to say, you use mkfs to
create the file system of your choice (ext2, ext3, etc.). Then mount and
write it. I've even played around with using squashfs to create & write a
compressed file system, with mixed results.
Cheers!
