Yeah that's where I got the idea from. Had told a friend what I was
doing and he came up with a very good point - the lifetime of a hard
drive is much greater than a cdrom drive so if you could reduce the
usage of the cdrom drive to only what was absolutely necessary, it
would hopefully stay relatively reliable for longer.

Of course this creates yet another issue. If you're using vm's, you
want to have the memory avaliable for the vm's whcih isn't going to
happen if you have dom0 loaded in memory.

Another issue just slapped me full in the face - of course the livecd
would have to have support for lvm2 and mdadm as well so that it could
access the vm images. :) Back to the very first problem. (The second
became trying to customize slax - mostly worked except that nothing
seemed to want to work off the cuff).

I think I'm going to have to try and get the money together to buy a
new hard drive.
