Can you use a templated unit for lircd? e.g. [email protected], afterall I presume you have to run a separate licrd for each serial port you have. If so, then your [email protected] file would contain something like: ExecStartPre=-/usr/bin/rmmod lirc_serial ExecStartPre=-/usr/bin/setserial /dev/%i uart none ExecStartPre=-/sbin/modprobe lirc_serial ExecStart=.... Not sure it's the most graceful of solutions and if you do have multiple remotes connected (admittedly a somewhat uncommon setup) then the rmmod will likely fail). Still you might be able to do what you need to do with ExecStartPre even in a non-templated unit that will do what you need it to.
