Description:
Basically upstream irexec.service needs to be updated (see http://sourceforge.net/p/lirc/tickets/29/).

May I however suggest to remove the Wants line altogether, as there are several other packages (such as eventlircd and inputlirc) which works nicely together with irexec.
Adding dependencies with drop-in files (/etc/systemd/system/irexec.service.d/*.conf) is easy, removing them on the other hand is not.[1]
This task depends upon

Wants is fine to leave in. A failure (including non-existence) of a wanted dependency doesn't result in any service-level failure. The thread you reference talks about BindsTo, which is a stronger type of dependency, similar to Requires. A failure here from a dependent service *will* cause a service-level failure.

Because both lircd.service and irexec.service are in the same package (lirc-utils) it will always be existent, hence lircd will be started if irexec is started.
Splitting the package might be a solution?

Right, that sounds *much* better than the alternative of starting irexec.service out of the box and having it fail. If you want to switch lircd providers, then just mask lircd.service and add your own Wants.

Oh masking, right totaly forgot about that possibility. Thanks!
