So according to this site here:

http://www.knoppix.net/wiki/Knoppix_...ring_Howto#APT

Warning: apt-get upgrade is a BAD IDEA. It will, quite probably, render your KNOPPIX remaster unbootable, or broken in some way. A far safer method is to only upgrade packages as necessary.
So... I know that what I want to do *WILL* require me using apt-get. But I don't want to break my newly customized Knoppix remaster.

I've seen other remasters, based on Knoppix, that are totally bootable. So I KNOW that using apt-get and STILL having a bootable remaster is possible.

How?

I haven't been able to find any decent info on this how... Can anyone point me in the right direction???\

Thanks...
