Re: [Xen-users] update-rc.d: warning: xencommons

[cyberhawk001@xxxxxxxxx]

Well, that makes perfect sense. I just figured it was strange that all 
previous revisions of Xen 4.2-Unstbale gave a warning at xencommons 
only, and the latest one gives you a lot more warnings and with all 4 
init scripts. But, will just ignore that as well.
