[OE-core] [PATCH v9] kernel: Add support for multiple kernel packages
Burton, Ross

Mon Dec 4 16:13:41 UTC 2017
I know I'm late and this has gone through so many revisions, but I'm seeing
unexplained changes in buildhistory:
$ buildhistory-diff
packages/corei7-64-intel-common-poky-linux/linux-intel/kernel-image-bzimage:
FILELIST: removed "/boot/bzImage"
Doing builds of virtual/kernel with and without this patch and comparing
pkgdata directly confirms that the /boot/bzImage symlink doesn't exist with
this patch but does without it.
