Thanks for your input
That would mean that every six month an upgrade could be done, without the need to rebuilt from scratch. Eventually, we could still rebuild a server from scratch every X years if needed. Combined with third party patch providers like M:Tier to makes the whole proces of security patching quicker, that sounds like something more doable than what I first though
I may try to suggest that on my work place, who knows...
