Systemd continues to baffle me.



I've set up a router machine that provides pxe boot and tftp services on a 

private network with dnsmasq.  Pxeboot works if I run dnsmasq manually, but not 

when I turn on the service with systemctl.



I can't think through its layers of obtuseness and would appreciate someone with 

a fresher brain to point me in the right direction.
