I just finished reviewing the slides for LTSI given at ELC: 
(https://events.linuxfoundation.org/images/stories/pdf/lf_elc12_shibata.pdf). 


Why does the Linux Foundation need to get behind yet another effort to 
maintain a kernel repository for embedded?  It seems that many of the 
objectives are the same for the two projects regarding the kernel.  Why 
not just branch a yearly Yocto kernel as long-term stable and add the 
support methodology outlined in the LTSI slides to this branch?  Perhaps 
this could also be done with the Poky repo?

How is a developer supposed to view Yocto and LTSI?  The former is 
cutting edge, developer friendly with all the bells & whistles, and 
experimental but use the latter for production???  Or maybe use the 
tools and rootfs from Yocto but the kernel from LTSI?

It seems Greg K-H of LTSI should join forces with Yocto and keep things 
simple & unified for us embedded developers (or Yocto should dump 
maintaining its own kernel repos and just draw from LTSI).
