Open Stack

Stanislaw,

I agree that this approch would work well. However, does Puppet allow
managing capabilities and/or file ACLs? Or can they be easily set up when
installing RPM package? (is there a way to specify capabilities/ACLs in the
RPM spec file?) This doesn't seem to be supported out of the box.

I'm going to research if it is possible to manage capabilities and  ACLs
with what we have out of the box (RPM, Puppet).
