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).
