# 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).

Perform additional tweaks to units Use RemainAfterExit to avoid pvc-flush from auto-stopping immediately. Use PartOf to tie services to the target itself. Use --wait on flush to avoid daemon stopping before flush is complete.

Move to YAML config and allow split functions 1. Move to a YAML-based configuration format instead of the original INI-based configuration to facilitate better organization and readability. 2. Modify the daemon to be able to operate in several modes based on configuration flags. Either networking or storage functions can be disabled using the configuration, allowing the PVC system to be used only for hypervisor management if required.
