The dunst package ships org.knopwob.dunst.service with
Name=org.freedesktop.Notifications, so D-Bus auto-activates dunst the
moment any app posts a notification, beating beacon to the name (beacon
then exits on name-lost). Shadow it with a user-level activation file
that Execs beacon-start.sh; ~/.local/share/dbus-1/services takes
precedence over /usr/share. Documented the install-time deploy in
updater.conf.
