if so, what should I do? 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!
