After having done a couple of 7.0.5 remasterings after different levels of purging, I think I have to warn, generally, against purging. Too many packages are removed, and worse still, reinstalling the dysfunctional programs doesn't always fix the problems. I have still not been able to get konqueror up and running, even with no extensive purging of KDE packages. This is a new problem, the same methods have worked fine on earlier Knoppix releases. It is also quite frustrating to have a system that seems to work well, but then suddenly something is broken, and the standard ways to fix it don't work. So, if KK would leave about a GB worth of space on the DVD (about the size of installed games), it would be very helpful to us who need to remaster to accomodate large extra installs. Purging used to be a safe and nice thing to do, I can't say it is anymore.
