#### New service name: lirc -> lircd.

For reasons of consistency we have renamed the lirc service to
lircd. Basically, this means that to start the service one need
to use systemctl start lircd.service instead of lirc.service etc.
Sorry for the inconvenience.

#### Enable lirc protocol

For lirc to work with ir devices, the lirc protocol must be enabled
for the actual device used. This only applies to ir devices which
are visible as /sys/class/rc/rc? devices. E. g., I have an RF remote
which is just an usb device (driver atilibusb) and this one does
*not* require the the lirc protocol to be enabled in this way.

If you have a "classic" ir device needing lirc to be enabled one option
is to install the lirc-disable-kernel-rc subpackage. This is an udev
rule which disables the kernel built-in ir device handling and makes
lirc the only protocol used. This might or might not be what you want.

Another option is to set the LIRCD_IR_DEVICE in /etc/sysconfig/lirc. This
will enable the lirc protocol for that device when lirc is running. The
kernel built-in protocols are still in place, but not used. Again, this
might or might not be what you want.

#### Socket activation

As of 0.9.4-15+, the Fedora lirc package sports systemd socket
activation. This should fix the problems at startup when clients can't
connect to /var/run/lircd because the lircd service is yet not started.

To start the lircd service using socket activation:

    # systemctl enable lircd.socket
    # systemctl start lircd.socket

The lircmd is started the usual way:

    # systemctl enable lircmd.service
    # systemctl start lircmd.service

#### Running another instance.

Sometimes another lircd instance is required to handle some other input
device. This could be done by creating a new service definition in
/etc/systemd/system.

In my case I have an extra instance handling ir output to the transciever.
This is accomplished with  a file /etc/systemd/system/lirc-tx:
----------------
[Unit]
Description=LIRC Infrared Signal Decoder
After=network.target

[Service]
Type=simple
ExecStart=/usr/sbin/lircd --driver=iguanaIR \
                          --device=/var/run/iguanaIR/0 \
                          --output=/var/run/lirc/lircd-tx \
                          --pidfile=/run/lirc/dont-use-lircd-tx.pid \
                          --nodaemon \
                          --allow-simulate

[Install]
WantedBy=multi-user.target

-----------------------

This defines a new service which can be started using
'systemctl start lirc-tx' etc. It's essential that each service has an
unique output socket. You should probably also think twice before running
two instances with the same input device.
