Do you want to simultaneously run ZFS and SecureBoot on ucore ? We’ve got you covered!
On your next update, you’ll have zfs kmods signed with the same signing key we use to sign kmods for our Universal Blue desktop images.
We have notes on using the key for SecureBoot here: GitHub - ublue-os/ucore: An OCI base image of Fedora CoreOS with batteries included
PS: the nvidia kmods are also signed with this key.
