[Thomas Mueller <thomas@chaschperli.ch>]

Hi

I wanted to do some testing. but i failed on mkcephfs.  see mkcephfs 
output below. 

this is on debian lenny, i follow the howto in the wiki http://
ceph.newdream.net/wiki/Debian and 
http://ceph.newdream.net/wiki/Installing_on_Debian

0.19 worked with the wiki-howto.

.. and what happend to the ceph-kclient-source package?
