FYI there is a shortcut to creating these - the "recipetool appendfile" 
command. For example, say you have your desired custom inittab file locally as 
"myinittab" and you want the bbappend to be created in meta-mylayer then you 
would run:

recipetool appendfile meta-mylayer /etc/inittab myinittab

This will automatically determine which recipe is providing the file and how 
to overwrite it with your version. You do need to have built that recipe for 
this to work, but then that will already be the case if you have built the 
image beforehand.

Cheers,
Paul
