Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

`nixos-generate-config` detects the `cpuFreqGovernor` suited best for my
machine, e.g. `powerManagement.cpuFreqGovernor = lib.mkDefault "powersave";`.
However the `powerManagement` module sets a sensitive default for
`cpuFreqGovernor` using `mkDefault` to avoid breackage with older
setups. Since 140ac2f1 the `hardware-configuration.nix` sets the
gorvernor with `mkDefault` as well which causes evaluation errors if the
powermanagement module is enabled:
```
error: The unique option `powerManagement.cpuFreqGovernor' is defined multiple times, in `/home/ma27/Projects/nixos-config/hardware-configuration.nix' and `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/nixos/modules/config/power-management.nix'.
```
Using `mkOptionDefault` rather than `mkDefault` in the powermanagement
module fixes this issue as it decreases the priority of the module and
prefers the value set in `hardware-configuration.nix`.
I have confirmed the change using the following VM declaration:
```
{
cpuFreq = { lib, ... }: {
powerManagement.cpuFreqGovernor = lib.mkDefault "powersave";
powerManagement.enable = true;
};
}
```

Commit 987aac7 and issue #18183 were intended to fix support for other
things, but in the process, changed mdns_minimal to use the wrong return
setting, resulting in permanent failures in early boot, affecting things
like issue #30459.

This reverts commit 670b4e29adc16e0a29aa5b4c126703dcca56aeb6. The change
added in this commit was controversial when it was originally suggested
in https://github.com/NixOS/nixpkgs/pull/29205. Then that PR was closed
and a new one opened, https://github.com/NixOS/nixpkgs/pull/29503,
effectively circumventing the review process. I don't agree with this
modification. Adding an option 'resolveLocalQueries' to tell the locally
running name server that it should resolve local DNS queries feels
outright nuts. I agree that the current state is unsatisfactory and that
it should be improved, but this is not the right way.

When the user specifies the networking.nameservers setting in the
configuration file, it must take precedence over automatically
derived settings.
The culprit was services.bind that made the resolver set to
127.0.0.1 and ignore the nameserver setting.
This patch adds a flag to services.bind to override the nameserver
to localhost. It defaults to true. Setting this to false prevents the
service.bind and dnsmasq.resolveLocalQueries settings from
overriding the users' settings.
Also, when the user specifies a domain to search, it must be set in
the resolver configuration, even if the user does not specify any
nameservers.

This commit was accidentally merged to 17.09 but was intended for
master. This is the cherry-pick to master.
In order for DynamicUser = true to work in services, we need the
nss-systemd module to be able to resolve the user and group names
generated dynamically.

If the value for timeZone is null it shouldn't be even tried to coerce
it into a string.

Creating and then erasing the key relies on the disk erasing data
correctly, and otherwise allows attackers to simply decrypt swap just
using "secretkey". We don't actually need a LUKS header, so we can save
ourselves some pointless disk writes and identifiability.
In addition, I wouldn't have made the awful mistake of backing up my swap partition's LUKS header instead of my zpool's. May my data rest in peace.
