Hi Egbert,

thank you for maintaining the PPA. I am using it and it works great on my se=
rvers. I wish the version bumps would happen more often as long as the code i=
s experimental. Testing "old" code does not make too much sense (I think we m=
ailed a couple of days ago about that). Other from that I strongly support E=
gbert's PPA becoming the official one. Had no problems so far and I like the=
 test setup.

Cheers,

Dan
