[yocto] Yocto with Initial RamFS

[Brian Smucker]

Hello,

I have an initial ramfs image that I want to convert to Yocto. That is 
in addition to the main yocto-based custom distro.

The initial ram fs is a tiny image based on uclibc (poky-tiny) and 
having busybox and two other compiled apps.  The main file system is 
eglibc-based.

How is this sort of thing typically done in the Yocto world?  Since the 
toolchain is totally different for the initial ramfs, do I need to have 
another distro and totally different directory for creating the 
initialramfs, giving two different distros and yocto directories?  Or 
can I somehow do it under the umbrella of one Yocto distro?

I would like some feedback on how this should be done.

Thanks,

Brian
