Description of changes

I’m on the fence about backporting the changes to latestCompatibleLinuxPackages—it does make backporting and maintenance a lot easier. It should also ease backports for Kernel updates and removals as it decouples the ZFS drv from them somewhat. My hesitation is simply that it is a more “substantial” change.

Leaving this draft for a bit for discussion re above and also to let 2.2.6 sit on unstable for a bit before backporting.

(cherry picked from commit 52a7570)
This removes the need to micromanage this value, instead we simply find
the correct one based on the existing kernelCompatible attr (though that
is now a function). This not only simplifies ZFS upgrades, but also
whenever Kernel versions are removed due to EOL.

(cherry picked from commit 7fa05c7)
(cherry picked from commit 34e1748)
(cherry picked from commit d174eca)
- This release brings official support for Kernel 6.10
- Also update zfs_unstable as it would otherwise lag behind
- Upstream now links `zpool` completion, so only do so on older zfs
  (since we still need to support 2.1.x)

I built release-24.05 from commit c5672ec7cbac38685781356e7c24595028c810b2 and I received a libre kernel. This is unexpected? Presumably most users would want a non-libre kernel so that they can load binary firmwares for wifi cards, processor, etc.

Repro:

-bash-3.2$ git checkout c5672ec7cbac38685781356e7c24595028c810b2
Note: switching to 'c5672ec7cbac38685781356e7c24595028c810b2'.

Indeed unexpected. The problem is that 24.05, unlike unstable, does not set an alternative pname for linux-libre. Oy. I’ll have a PR later today.

Additionally, I would generally recommend against using latestCompatibleLinuxPackages at all—your Kernel can (and will) go backwards at times.

This is good advice; recent wifi chipsets seem to be quite dependent on having a newer kernel version, and the recent downgrade to 6.6 on nixos-24.05 for ZFS resulting from the deprecation of 6.8 and 6.9 broke my wifi card until I replaced my use of latestCompatibleLinuxPackages.

latestCompatibleLinuxPackages needs to go but in the mean time we must unbreak stable: #341867

I'm going to revert the commit.

You prefaced this with being on the fence about but next time, please don't backport such changes. They're bound to run into issues like this and it's better to just eat the minor maintenance overhead for the next few months (isn't that like 2 PRs max anyways?).

We really should not break stable like this.
