This shouldn’t be a problem. With each kernel update, zfs module and spl module need to be rebuilt. DKMS should take care of this, but of course, if this fails, you won’t be able to boot your system.
Recent kernel updates didn’t trigger zfs/spl module recompilations anymore. Did someone put in place changes on how to handle ZFS with non-LTS kernels or do I have instead a configuration quirk since the last zfs/kernel issues and therefore dkms doesn’t trigger anymore?
