They have such low process numbers I've always thought they were all absolutely essential. Can I mess with them?

I actually DO ssh into the laptop sometimes -- not often, but sometimes when transfering data I want to work excluseively on my desktop... but I ought to be able to turn it off without any problem, I'll do that. I don't really know what xfs is for -- occasionally I do work in a gui on Openoffice -- since fonts were so hard to set up I'm loathe to mess with them, but if in fact xfs is always unnecessary I'll just get rid of it. I just checked and the only other package apt wants to remove with it is x-window-system. Do you think that makes it safe to remove it? Portmap I'll get rid of right now. well, that's a start -- thanks! matt
