Hi, I have just rebased my patch for splitting the ZFS package into separate user-space tool and kernel module packages, to resolve the merge conflict from the current ZFS package being updated to a newer version. The patch can be found at https://issues.guix.gnu.org/71482.
Among other things means that neither the default linux-libre kernel nor the ZFS kernel module for that kernel have to be built when one is using a different kernel package. This is particularly noticeable if one references the existing zfs package for the sake of having the tools available. Currently one has to be careful to ensure that only the custom zfs package derivative is referenced in the list of operating-system packages and any services or other packages that might depend on the user-space tools (such as zfs-auto-snapshot) to avoid having to download and/or build a kernel and matching module that isn't used. Cheers, Kaelyn
