Hi Anders, Thank you I’ll definitely try this out.
A couple of questions, What is the status of this feature, is it scheduled to be included in a release? Do you have a list of services that need to be disabled? What OSAF version is this based on? 5.4? thanks — tony > On Oct 12, 2015, at 10:07 AM, Anders Widell <[email protected]> > wrote: > > We have actually implemented something very similar to what you are talking > about.
