This re-introduces the old stable ZFS version we had in the past following
the many predicted issues of ZFS 2.2.x series, that is much more stable
than any further ZFS version at the moment.
I am also removing myself from maintenance of any further ZFS versions as I am
planning to quit ZFS maintenance at some point.
In the meantime, for users like me who depend on ZFS for critical operations, here is a ZFS version
that is known to work for LTS kernels.
Being wanted by and ordered before local-fs.target isn't strictly
correct. And in systemd initrd, it's very incorrect because
local-fs.target is for the initrd file system, not the real root file
system.
a zfs fileSystems entry with an absolute (e.g. device) path rather than
a zfs dataser is parsed as an empty pool name, causing a doomed-to-fail
import job to be created as a boot dependency. Catch this as an assertion
Currently systemd-ask-passwd times out after 1m30s. After 3 tries this
causees systemd to enter the emergency shell and basically lead to an
unbootable system requiring a reboot to be able to try to unlock again.
Also if a pool is imported but not unlocked, the unlock step will no
longer be skipped.
Enable using an erofs filesystem as one of the filesystems needed to
boot the system. This is useful for example in image based deployments
where the Nix store is mounted read only.
[erofs](https://docs.kernel.org/filesystems/erofs.html) offers multiple
benefits over older filesystems like squashfs. Skip fsck.erofs because
it is still experimental.
According to a ZFS issue about hibernation causing data corruption:
https://github.com/openzfs/zfs/issues/12842
The way this happens is if the system force imports a pool that was
suspended during hibernation. I've had this happen twice on NixOS and
I'd like to avoid having this happen again, to me or others.
To do this I've added an assertion that makes sure you can't have
`forceImportRoot` or `forceImportAll` enabled with `allowHibernation`.
