Hi Petr,

thanks for the very quick response!

Thanks! That made way more clear what you meant.

Great! I really wondered about that "No" there. :-)

Will add these questions and answers to the wiki either later this
afternoon or late this evening since I give a kfreebsd talk at our LUG
this evening. So I'm quite happy that I can add the answers to these
questions already to the slides for this evening. :-)

P.S.: Tolimar will also give a Debian GNU/kFreeBSD talk at CeBIT based
on these slides. See [1] for the announcement.

Cc to Tolimar so he gets that information, too.

		Regards, Axel
