[systemd-devel] systemd-networkd doesn't delete netdev when parent interface is deleted

[hello at andreborie.name]

What workaround do you suggest in the meantime ?

I'm currently using a very ugly hack which is an oneshot service that 
runs "ip tunnel del" right before the PPP service starts (and ignores 
eventual errors); is there a better way, possibly without touching the 
actual PPP service file (I'd like the tunnel to be self-contained in its 
netdev files).

	# /etc/systemd/system/ppp at orange.service
	[Unit]
	Description=PPP link to %I
	After=network.target tunnel-delete.service
	Wants=tunnel-delete.service

	[Service]
	Type=forking
	PIDFile=/run/ppp-%i.pid
	ExecStart=/usr/sbin/pppd call %I linkname %i updetach
	SuccessExitStatus=5
	Restart=on-failure

	[Install]
	WantedBy=multi-user.target

	# /etc/systemd/system/tunnel-delete.service
	[Unit]
	Description=Delete remaining tunnel
	BindsTo=ppp at orange.service

	[Service]
	Type=oneshot
	ExecStartPre=-/bin/ip link set down dev heipv6 # horror starts here
	ExecStart=-/bin/ip tunnel del heipv6 # more nightmares
