zfs: Temporarily use git sources for hawk
subsonic: Just turn off the service for now--I'll may fully disable it later
nest: Add beets music manager
openvpn: Create client profiles for mobile devices; use tun instead of tap
networkmanager: Use plasma-nm instead of legacy kde-networkmanager

This requires deselecting kde-misc/networkmanager from @world, but I
don't feel like doing this in Puppet.  Let it fail and I'll fix
manually.
