That was basically what I was guessing
But Jacqui is extremely knowledgeable about all aspects of the system, and I was wondering if he had something to say about core system files as opposed to apps or desktops. He's a compiling dude, rather than a binary-installing guy.
I'll look into Ice WM. I've never tried it. I'll probably be installing Etch with XFCE, and adding e16 to it. I'll probably be trying out Fluxbox and others as well. I don't need a super-lean desktop, but I generally don't want Gnome or KDE, simply as a matter of taste, although I'm sure they are much improved over the versions I had been using with Shrike (I was just a bit out of date, what can I say?).
