[yocto] Per image customizations

[Oleksandr Poznyak]

Hi,
Unfortunately You can't have two *.bbappend files per one package (recipe).

You can create two new recipes where You'll install what You need and plus
add sysvinit-inittab to DEPENDS variable in those recipes. This will help
to retain the order of packages installation. Original sysvinit -> your
sysvinit.

In this situation You will have several recipes.

Thanks,
Oleksandr Poznyak!
