As has already been pointed out, it is possible to burn different file system
types to cd. In fact, a file system isn't even necessary as I discovered one
time when I accidentally gave cdrecord a tarball as input rather than the iso
image. No trouble accessing the file thanks to the magic of *nix... just had
to give tar the device rather than mounting it: tar xzf /dev/cdrom. he he.

At the time I tried doing it I was attempting to incrementally build a file
system for archival purposes... something mkisofs can't do as it's not a
'real' read/write filesystem. I built a 650M ext2 file system in a file,
mounted loopback. I could daily add files to be archived and write it to cd
when the file system was full. Ended up being too much work though.
