Thanks, I've applied your patch after doing a number of
fixes/improvements to it. See below.

Missing dependency on BR2_USE_MMU, since fork() is used in lirc-tools.

Lines too long, the text should be wrapped to a smaller length.

This doesn't make much sense if there is no indication about what this
means, so I've removed this part.

I've slightly reworded since, and removed the space before comma.

This means that re-execution of the start step is not possible. I've
changed that to 'mkdir -p'.

Same issue, I've changed to 'ln -sf'.

With this, lircd continues to daemonize itself, so the pid stored in
/var/run/lirc.pid is not the real PID of the lircd daemon. I've changed
this to pass the '-n' option to lircd so that it doesn't daemonize
itself.

A full destination path is what we use when calling $(INSTALL), so I've
changed this as well.

But the most problematic issue was actually that your new package
Config.in file was not included anywhere! Seems like you forgot to 'git
add package/Config.in'.

Committed with those issues fixed, see
http://git.buildroot.net/buildroot/commit/?id=1ba7e76d5786114e05482ae6528e6da61eb12be3
for more details.

Thanks,
