Hi Greg & Sasha !

I ran into some trouble in my nightly CI systems that test v6.6.y and v6.1.y. Using "make binrpm-pkg" followed by "rpm -iv ..." results in the test systems being unbootable because the vmlinuz file is never copied to /boot. The test systems are imaged with Fedora 39.

I found a related Fedora bug:

https://bugzilla.redhat.com/show_bug.cgi?id=2239008

It appears there is a missing fix in LTS kernels. I bisected the kernel fix to:

358de8b4f201 ("kbuild: rpm-pkg: simplify installkernel %post")

which includes a "Cc: stable" tag but does not appear in origin/linux-6.6.y, origin/linux-6.1.y, or origin/5.15.y (I did not look further back than that).

Would it be appropriate to apply 358de8b4f201 to LTS kernels?

Perhaps, if someone actually backported it to apply there, did you try it? :)

At the time, this was reported: https://lore.kernel.org/all/2024021932-lavish-expel-58e5@gregkh/ https://lore.kernel.org/r/2024021934-spree-discard-c389@gregkh https://lore.kernel.org/r/2024021930-prozac-outfield-8653@gregkh but no one did anything about it.

I've posted a clean and tested backport to v6.6 LTS.

However, the number of patches that need to be applied to v6.1 is much larger than the provided possible dependency list. Hence my original question "Would it be appropriate ..." I think therefore that the answer is "It would not be appropriate to apply 358de8b4f201 to LTS kernels prior to origin/linux-6.6.y".

And perhaps the solution for me is to ensure my v6.1.y test runners use Fedora 37 instead of Fedora 39.
