I was annoyed at how much disk space seemed to be taken up with stuff I
didn't install (not on purpose): I had a 1 Gb drive that was 95% full.
So I decided to reinstall from CD.
Big mistake, it turns out. Got lots of space back but I can't load my
cdrom drive now: the device was never created and I have no idea what
the modes might be. Once I get that done, I can install KDE and the rest
of the stuff I use.
