Interesting. What kind of Live CD do you have? Have you ever thought of
making one that pulls the kernel off the user's system, and allows the user
to *easily* add his own directories to the CD? Doing so would make it very
useful for creating rescue CDs.

I don't think so. It depends on what kind of data you have. Perhaps someone
on one of the Bacula lists would have some comments.

If you are looking for good compression, you probably should think about using
some other algorithm. I don't know which one is the best, but even bzip2
gets about 20-30% better compression than gzip.
