thanks for the report, I did put it on the list.
Can this trivial patch be put in portage? kexec failures are really annoying.

If someone have a separate /boot, then both kernel image and initrd should be there. This patch omits only initrd check and keeps kernel image check. For Gentoo it is very natural not to use initrd at all, because most user kernels are custom build kernels, and obviously you do not need initrd if you build your own hardware specific kernel except for several really rare cases.

This patch omits only > initrd check and keeps kernel image check. I think you are right. Then the real test should be with and instead of or. if [[ -z "${img}" ]] && [[ -z "${initrd}" ]] > > For Gentoo it is very natural not to use initrd at all, because most > user kernels are custom build kernels, and obviously you do not need > initrd if you build your own hardware specific kernel except for several > really rare cases. Agree I have never needed a initrd.

But I can't imagine a case where kernel image is not available, but initrd is.

But I can't > imagine a case where kernel image is not available, but initrd is. Hmm, I changed my mind again. :) That test would be bad for someone having a separate /boot but no initrd in it. Back to just testing for ${img} again. That is the best solution.
