There is no canonical way to set a system domain name any longer. The one
we previously used was the NIS/YP one, but that is pointless these days.
The hostname is set up through /etc/hostname, but hostname(5) states that
it should only contain 64 7-bit ASCII characters, so it cannot be used
to cover the domain name.
We still support setting the domain name to complete the `fqdn` option
and as a central option to reference the domain name from. If anyone
wants a NIS/YP domain name set, do it yourself..
We then clarify that the domain option has nothing to do with DNS
resolution anymore and search should be configured instead.
Finally explain the purpose of the ndots option in the context of search
domains, since they decide when we stop considering the search domains
when querying names with more than one dot.
The `domainname` utility uses setdomainname (see getdomainname(2)) to
configure the NIS[1] (also known as YP) domain name.
It provided a central directory for various objects that are resolved via
nsswitch in the late 1990s and early 2000s.
It is however not a safe nor common deployment scenario anymore.

This is first and foremost to provide compat with scripts that call the
hostname executable to retrieve the hostname, an assumptions we probably
should not be breaking.
This will allow unlocking to take place *after* all of the devices have
been probed, as indicated by the x-systemd.wants and x-systemd.requires
options. This allows for multi-device bcachefs volumes to be reliably
unlocked.
Kernel 6.16-rc1 removed the poly1305 algorithm in
ceef731b0e22df80a13d67773ae9afd55a971f9e
bcachefs switched to the kernel libraries for poly1305 and chacha20 in
6.15 in 4bf4b5046de0ef7f9dc50f3a9ef8a6dcda178a6d
When auto-upgrading based on a flake, it might be desirable to
only upgrade to the newer flake, without updating the nixpkgs
from the flake lock. This option makes that possible.
Thank you for making this change.
Unfortunately, and I take blame for this, this change to the module
system was not reviewed and approved by the module system maintainers.
I'm supportive of this change, but extending it on the staging-next
branch is not the right place.
This commit is also here to make sure that we don't run into conflicts
or other git trouble with the staging workflow.
Review:
It looks alright, but it didn't have tests yet, and it should be
considered in a broader context where the existence of this type
creates an incentive to be used in cases where the `<attr> = false;`
case is undesirable. I'd like to complement this with an type that
has `<attr> = {};` only.
My apologies for the lack of a timely and clear review. Often we
recommend to define the type outside the module system until
approved. This commit puts us back in that state.

This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by

Otherwise, when doing nixos switch to major changes (typically when stdenv changes), udevd service gets loaded after addresses, which causes addresses service to wait indefinitely for the device and fail.

`lib.all (_: false) [ ]` is `true`, which is not the semantics we want
here, and interacts poorly with `boot.zfs.extraPools` where
`getPoolFilesystems` may return `[]`. So explicitly handle this case.
This does mean there isn’t a straightforward way to disable auto-import
with `extraPools` and no associated `fileSystems` while keeping the unit
around, but that’s probably okay for now.
See https://github.com/NixOS/nixpkgs/issues/364995.
Broken in 7f8278a264.
This requires all datasets for the pool specified in `fileSystems` to be
marked noauto.
Note that this implicitly skips some tasks for the pool, such as
`expandOnBoot`, as the pool will not be imported at that time.
