Comment 1 Darren Hart 2013-08-08 15:53:11 UTC 
Which images specifically? I just built core-image-minimal for qemux86 and the /boot directory in the ext2 image is empty.
Comment 2 Darren Hart 2013-08-08 15:54:51 UTC 
bah, apologies, was building poky-tiny on accident.
Comment 3 Darren Hart 2013-08-09 17:02:24 UTC 
This appears to be due to pkg_postinst_kernel-base making the alternatives link when it's kernel-image that installs the actual kernel image. Testing a correction.

    kernel.bbclass: Correct post(inst|rm) package association
    
    Fixes [YOCTO #4991]
    
    The kernel image is installed as part of the kernel-image package, but
    the symlink creation/removal via alternatives is being done in
    pkg_post(inst|rm)_kernel-base.
    
    Move the postinst alternatives logic into the kernel-image functions.
