[yocto] Yocto with Initial RamFS

[Brian Smucker]

Thanks Soren,

My followup question is: Can I mix toolchains in this situation?

Can I compile the initramfs binaries with the uclibc toolchain based on 
the poky-tiny distro and the regular file system binaries with the 
glibc-based toolchain (based on a different distro)?

If this is possible, how would I begin to do it?

Thanks,

Brian
