Build Identifier: 

When I tried dnf distro-sync --allowerasing --releasever=23 I got an error because dnf was going to remove the running kernel. So I tried dnf distro-sync --allowerasing --releasever=23 --exclude='kernel*' figuring that would skip any kernel updates. Instead they were all removed. If you notice before you reboot it is fixable. But if you don't, lots of fun can be involved. Especially with very old hardware.

Reproducible: Always

Just using dnf distro-sync --allowerasing --exclude='kernel*' doesn't trigger the bug. I mostly have rawhide nodebug kernels installed.
Comment 2 Bruno Wolff III 2015-09-28 16:25:03 UTC 
dnf distro-sync --allowerasing --exclude='kernel*' --disablerepo=fedora-rawhide-kernel-nodebug didn't trigger the issue either.

Raw typescript file from problematic upgrade

The typescript file is raw and has terminal escape sequences in it. (I started out using vi to fix some repo files pointing to a local mirror of f23.) But it might provide some insight into why the kernels all got removed.
