Re: [Xen-devel] Documetation - The Phantom Menace

["Mark A. Williamson" <mark.williamson@xxxxxxxxxxxx>]

Thanks very much!  That's really useful information to have!  I didn't know 
about debbootstrap - it's great that you can do that!  Can you install 
debbootstrap on non-debian machines?  That'd be even more useful!

I'll incorporate your howto into an appendix in the user manual - should be 
really useful!

Thanks again!  We'll be finished in no time ;-)
