Syntax errors prevent our Avahi run-late.conf from having any effect?

[SyntaxColoring]

#16 added this file to "Run avahi-daemon later than usual during boot so it actually picks up the changed hostname":

buildroot/board/opentrons/ot2/rootfs-overlay/usr/lib/systemd/system/avahi-daemon.service.d/run-late.conf

Lines 1 to 5 in a0b6147

	[unit]
	After=multi-user.target
	[install]
	WantedBy=opentrons.target

However, this might not be having any effect, since unit should be Unit and install should be Install.

• Investigate whether this is doing anything now.
• Investigate whether running Avahi late is still required.
• Investigate whether fixing this will break anything.

The lifetime of the avahi-daemon process is also a little intertwined with update-server. Currently, when update-server starts up:

• It will systemctl restart the Avahi process after setting the system's static hostname.
• It will open D-Bus connections to Avahi.
