stateless nodes? #646
Description
I wonder if it's a reasonable feature request to be able to use
stateless nodes, with root provisioned on NFS, a network block device,
or perhaps memory. That would finesse at least speed issues with
ansible provisioning, and is generally the best way to manage at least
less ephemeral clusters in my experience. I assume you can't PXE boot
a suitable initramfs with most providers, so you'd presumably need to
boot a minimal stateful system and trigger a pivot_root into the
appropriate filesystem from that.

Definitely something worth exploring!
I wonder how much "stateless" the nodes can be, though: each one would still need its own copy of the network config, and what else?
