Looking at recent zfs release note: https://github.com/openzfs/zfs/releases/tag/zfs-0.8.5and https://github.com/openzfs/zfs/releases/tag/zfs-0.8.6 Toggle quote (2 lines)
> * Compatible with 2.6.32 - 5.9 Linux kernels
zfs-0.8.6 includes a few "Linux 5.10 compat" but is still not rated for 5.10.
Would it be possible to fix this by adding `#:linux ,linux-libre-5.9` to the `arguments` field of the `zfs` package?
Of course, it does require that we use a specific linux version.
