I've been producing my own bootable DVD with stuff on it (both free things like SLAX and non-free things like Windows XP).
UBCD is a great tool and an essential requirement of such a disk but adding it is slightly awkward. It puts much of its stuff in the top level (root) directory.
To avoid clashing with other things that I wish to add, I have to move everything (except /boot I guess) to a subdirectory (/UBCD) and then go and fiddle with all the isolinux config files.
It's not hard to do this but it is error prone (I'd need to do a chunk of testing to check that I've got it right) and it's tedious (I'll need to repeat the work each time UBCD is updated).
Any chance that UBCD could hide itself under a subdirectory as much as possible?
I think it would make customising UBCD somewhat easier - it would certainly make things easier for me

By moving things to a subdirectory tree, the most I would have to worry about is other disks that use /boot. That's a much easier problem to solve even when adding a few Linux distros and/or Live CDs.
Thanks for a great tool BTW.
