Multiple LIRC Instances in systemd Service

[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

I'm trying to run multiple LIRC instances (one for each device) in a 
systemd service.

This is the error I'm getting:

lircd: could not assign address to socket
lircd: Permission denied

Either one of these two lircd commands run fine in a sudo terminal.

Two processes are trying to bind to the same port.
Change one "8765" to something else (8766?) or just leave out one of the
--listen arguments.

Thanks for your message.

If I understand this correctly. 8765 is the default listening port and 
connection port. So --listen=8765 always defaults to --listen. I tried 
both --listen and --listen=8765 but it still didn't work

No, you did not understand correctly. Read again, carefully. Or simply
put, start the first instance with

--listen=8765

and the second with

--listen=8766

LIRC Service not picking up systemd Environment File

[XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

Is there some issue with "EnvironmentFile=..." in systemd service file?

I'm trying to use this type of service file:

[Unit]
Description=LIRC Daemon
After=network.target

[Service]
Type=forking
EnvironmentFile=/etc/conf.d/lircd.conf
PIDFile=/run/lirc/lircd.pid
ExecStartPre=/bin/mkdir -p /run/lirc
ExecStartPre=/bin/rm -f /dev/lircd /run/lirc/lircd
ExecStartPre=/bin/ln -s /run/lirc/lircd /dev/lircd
ExecStart=/usr/sbin/lircd -d $LIRC_DEVICE -H $LIRC_DRIVER -P 
/run/lirc/lircd.pid $LIRC_CONFIGFILE
ExecStopPost=/bin/rm -fR /dev/lircd /run/lirc

[Install]
WantedBy=multi-user.target


But this is what I have to do to make it work:
I have to pass the arguments explicitly to /usr/sbin/lircd.

...
[Service]
Type=forking
EnvironmentFile=/etc/conf.d/lircd.conf
PIDFile=/run/lirc/lircd.pid
ExecStartPre=/bin/mkdir -p /run/lirc
ExecStartPre=/bin/rm -f /dev/lircd /run/lirc/lircd
ExecStartPre=/bin/ln -s /run/lirc/lircd /dev/lircd
ExecStart=/usr/sbin/lircd -d "/dev/lirc0" -H "devinput" -P 
/run/lirc/lircd.pid /etc/lirc/lircd.conf
ExecStopPost=/bin/rm -fR /dev/lircd /run/lirc
...

The "EnvionmentFile=/etc/conf.d/lircd.conf" contains:

LIRC_DEVICE = "/dev/lirc0"
LIRC_DRIVER = "devinput"
LIRC_CONFIGFILE = /etc/lirc/lircd.conf

Hi Geoff

Thanks but actually there are no white-spaces in the Env-file. I retyped 
the above with spaces on either side of '=' but actually in my real file 
there are no such spaces.

If I look up status:
# systemctl status lircd.service

I get:

 >> lircd: invalid argument count
