I am happy to hear that others find yaird usefull too.

And I am especially excited that you provide patches to make it work 
with recent kernels!

Your patches are not enough for me, however, and I wonder if you perhaps 
have applied other patches too, that might be relevant to include as 
well.

Yes, I think the comment is better suited in the man page - and should 
probably be added to the README as well.

You call it a Debian-specific modification.  Are you aware of yaird 
being used naywhere else than in Debian?


Kind regards,
