Tested. Yes, that works.
Is there something we can do on remove in order to stop the service?
I asked a colleague who is more familiar with systemd than I am, and he
pointed me to this link:
http://unix.stackexchange.com/questions/63232/what-is-the-correct-way-to-write-a-udev-rule-to-stop-a-service-under-systemd
However, when I run
systemctl list-units --all --full |grep .device
I get this for the Brailliant:
dev-brltty-auto\x2dusb:25000072.device
loaded active plugged Brailliant_40
dev-bus-usb-003-039.device
loaded active plugged Brailliant_40
So it appears that I need a fixed device name that systemd could bind to for
any Braille display. I've just tested having the udev rules file create a
symlink called "braille" and have systemd bind to it, and now it unloades
when I remove the display. Patch attached.
On second thought, that patch isn't right--it makes systemd require the
device in order to load brltty, which will break for a serial or a
bluetooth device.
