Subject: [Buildroot] [PATCH 1/1] package/quagga: Add systemd.service file
	and helper script
Message-ID: <1466269320-23938-1-git-send-email-nroach44@gmail.com>

We use a template service file as all of the daemons use almost
identical arguments and generally appear the same to the init
system.

We "Wants=" zebra as that's the daemon for interfacing to the
kernel, and it's not required for the other daemons to work
but it's probably going to be used in nearly all setups.

We need the helper script as systemd doesn't like having the
instance (%i) in the path to the executable.
