[yocto] Custom conf files

[Jaap de Jong]

Hi,

I'm just wondering what the best practise is for configuration files 
that I want to change for a specific image.

F.i. a simple one: /etc/issue

I could create a bbappend for the responsible recipe. Or I could add a 
ROOTFS_POSTPROCESS_COMMAND and patch in my changes

Are there other options?

What is the best practice?

Thanks!
Jaap
