Don't need the same level of availability. Worst case, I'm a bit annoyed and rebuild the OS and restore the configs from backup. Now I just need to figure out jails and bhyve for the services since I haven't worked with either before :) There's a couple of bhyve front ends I've been looking at, sorta on the fence for which one. Really I just need to pick one and run with it. --Aaron On Thu, May 18, 2017 at 5:05 AM, krad wrote: > The big question is what availability do you need on this server?
