[Pkg-zfsonlinux-devel] Bug#1024326: Bug#1024326: bullseye to bookworm upgrade failure: Could not locate dkms.conf file

[M. Zhou]

Control: severity -1 important
Control: tags -1 +moreinfo

I'm still not sure about why the upgrade failed, and I could not
reproduce the problem in a clean chroot using the following script:

https://salsa.debian.org/zfsonlinux-team/zfs/-/blob/master/debian/tests/sbuild-shell-bullseye-to-bookworm.sh

So I'm downgrading the bug's severity to unblock migration.
