I was going to suggest accessing unsupported filesystems by reading the
device as a stream, but seem to recall trying something similar in the
past and finding that because the partition it represents is a fixed
size (and files can be scattered anywhere over it) you always end up
with a file as big as the partition size, regardless of how much of the
space you've actually used. This means the maximum size (not just used
space) of any partition you want to copy to CD using the "cat /dev/hda1
| cdrecord -dev 0,0,0 -" method must be smaller than the capacity of
the CD.
Not that all this stops it from being a useful solution, but something
to bear in mind. Also, depending on the size of your filesystem and how
much of it is used, you could be waiting for a lot of free space to be
written to the CD.
