-- upgraded. We care about the case where a package is initially

-- installed, because other cases are covered by the *un scriptlets,

-- so sometimes we will reload needlessly.

%transfiletriggerun -p <lua> -- /usr/lib/systemd/system /etc/systemd/system

-- On removal, we need to run daemon-reload after any units have been

-- removed. %transfiletriggerpostun would be ideal, but it does not get

-- executed for some reason.

-- On upgrade, we need to run daemon-reload after any new unit files

-- have been installed, but before %postun scripts in packages get

-- executed. %transfiletriggerun gets the right list of files

-- but it is invoked too early (before changes happen).

-- %filetriggerpostun happens at the right time, but it fires for

-- every package.

-- To execute the reload at the right time, we create a state

-- file in %transfiletriggerun and execute the daemon-reload in

-- the first %filetriggerpostun.
