Nexus increased their default minimum disk space requirement to 4GB:
```
com.orientechnologies.orient.core.exception.OLowDiskSpaceException: Error occurred while executing a
write operation to database 'OSystem' due to limited free space on the disk (1823 MB). The database
is now working in read-only mode. Please close the database (or stop OrientDB), make room on your hard
drive and then reopen the database. The minimal required space is 4096 MB. Required space is now
set to 4096MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit) .
server# [ 72.560866] zqnav3mg7m6ixvdcacgj7p5ibijpibx5-unit-script-nexus-start[627]: DB name="OSystem"
```
Including the rest on the VM 8GB should be the most suitable solution.
As the installer test also takes 8GB of disk size this should still be
in an acceptable range.
cleanSource does not appear to work correctly in this case. The path
does not get coerced to a string, resulting in a dangling symlink
produced in channel.nix. Not sure why, but this
seems to fix it.
Fixes#51025.

Symlinking works for most plugins and themes, but Avada, for instance, fails to
understand the symlink, causing its file path stripping to fail. This results in
requests that look like:
https://example.com/wp-content//nix/store/...plugin/path/some-file.js
Since hard linking directories is not allowed, copying is the next best thing.

slub_debug is used to enable additional sanity checks and "red zones" around
allocations to detect read/writes beyond the allocated area, as well as
poisoning to overwrite free'd data.
The cost is yet more memory fragmentation ...
While at it (see previous commit), using attrNames in combination with
length is a bit verbose for checking whether the filtered attribute set
is empty, so let's just compare it against an empty attribute set.

When generating values for the services.nsd.zones attribute using values
from pkgs, we'll run into an infinite recursion because the nsd module
has a condition on the top-level definition of nixpkgs.config.
While it would work to push the definition a few levels down, it will
still only work if we don't use bind tools for generating zones.
As far as I could see, Python support for BIND seems to be only needed
for the dnssec-* tools, so instead of using nixpkgs.config, we now
directly override pkgs.bind instead of globally in nixpkgs.
To illustrate the problem with a small test case, instantiating the
following Nix expression from the nixpkgs source root will cause the
mentioned infinite recursion:
(import ./nixos {
configuration = { lib, pkgs, ... }: {
services.nsd.enable = true;
services.nsd.zones = import (pkgs.writeText "foo.nix" ''
{ "foo.".data = "xyz";
"foo.".dnssec = true;
}
'');
};
}).vm
With this change, generating zones via import-from-derivation is now
possible again.

This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
