# Parallel Virtual Cluster node daemon unit file
Add node autoflush service and target Add a systemd service to manage node flush/unflush, useful during system startup and shutdown to avoid requiring administrator intervention for this to occur. This is optional and the service is not enabled by default, and the postinst script informs the administrator of this. Also adds a systemd target to collect the two service units together and provide an easy way to flush+shutdown or startup+unflush the entire PVC system. Closes #28

[Unit]
Massive rejigger into single daemon Completely restructure the daemon code to move the 4 discrete daemons into a single daemon that can be run on every hypervisor. Introduce the idea of a static list of "coordinator" nodes which are configured at install time to run Zookeeper and FRR in router mode, and which are allowed to take on client network management duties (gateway, DHCP, DNS, etc.) while also allowing them to run VMs (i.e. no dedicated "router" nodes required).

Description = Parallel Virtual Cluster node daemon
Remove systemd deps on zookeeper and libvirt This caused a serious race condition, since the IPs managed by PVC had not yet come up, but Zookeeper was trying to start and bind to them, which of course failed. Remove these dependencies entirely - the daemon itself starts these services during initialization and they do not need to be started by systemd first.

Use consistent naming of components Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the daemons are fully consistent. Update the names of the configuration files as well to match this new formatting. References #79

Add some time around noded startup/shutdown Otherwise, systemd kills networking before the node daemon fully stops and it goes into "dead" status, which is super annoying.
