Thanks for the feedback! So would a tagging system be useful? Right now you can declare dependencies on a single server, but maybe we can have it depend on at least one of the machines in a tagged group booting up?
I could see a group being useful, yeah. Must have one of [server0, server1, server2] to continue. Though there is a lot of bleed-over when talking about hypervisors and the boot order of VMs, since hypervisors generally can handle that, at least on their own node.
