Great. That makes things easier & faster.

I'm pretty foggy about the xvdc vs xvdc1 name differences but if I
understand what you're asking I did the first type. I'm not even sure
how I'd do the latter, or if I should. Any thoughts on that?
Anyway I used Suse SLED v10's auto-installation stuff to do it. The
part of the script for the xvdc device was

So it sounds like the 1st one is simpler. And can be done live or hot.
Maybe I should just redo the whole thing to use the "create a
filesystem on /dev/xvdc" way.
Any pointers on that one? I've tried to follow some of those
discussions, and just get lost. It seems like each message answers a
question someone's not asking. Maybe I didn't find the right list
yet, but so far it's all pretty confusing to me.
I found the Xen wiki site. But I couldn't find any stuff about which
way is the right or best approach, or especially how to do it.

I guess that's a good thing :-)
Thanks a bunch.
