For Nix 1, some environment variables were set when using distributed
builds requiring the Nix daemon to be managed by nix-darwin. However,
support for Nix 1 has been removed and no other environment variables
for Nix are set by default.
Disabling this is not supported as `/run` gets cleared out on every
reboot so it is necessary for ensuring that the `/run/current-system`
symlink exists.
This commit updates the nix.conf validation logic to accommodate
different versions of Nix. It introduces a conditional assignment
of the `showCommand` variable, which determines the appropriate
command to use based on the Nix version. For versions at least
"2.20pre", it uses "config show"; otherwise, it falls back to
"show-config". This change ensures compatibility across various
Nix releases.
This process was automated by [my fork of `nix-doc-munge`]; thanks
to @pennae for writing this tool! It automatically checks that the
resulting documentation doesn't change, although my fork loosens
this a little to ignore some irrelevant whitespace and typographical
differences.
As of this commit there is no DocBook remaining in the options
documentation.

These all use DocBook markup too complex for `nix-doc-munge` to handle,
have syntax that clashes with Markdown, or already contain Markdown
syntax that currently isn't rendering correctly.
Converting DocBook list syntax makes me think that maybe Markdown
isn't so bad after all.
These help `nix-munge-doc` automate more of the Markdown conversion
process. See the following nixpkgs commits for explanations of many
of these changes:
* 275a34e0d8
* 694d5b19d3
* f1d39b6d61
* 16102dce2f
I couldn't think of any particularly good way to format the
`system.defaults` breadcrumbs, so I just made them standalone
paragraphs. They weren't rendering correctly in DocBook anyway.
This was
mkDefault { } // filterAttrs () x
which is interpreted as
(mkDefault { }) // (filterAttrs () x)
but the intention is
mkDefault ({ } // filterAttrs () x)
Resulting in lastModified, rev, etc. not being included. This is
essentially just bringing this clause up-to-date with the one from
NixOS.
Stop using `nice` related options like NixOS, and because `launchd`
recommends using `ProcessType` instead. Note this commit also changes
the default `ProcessType` for the `nix-daemon` from `Interactive` to
`Standard`.
Also remove `nix.version` option since it's no longer being used
anywhere, old irrelevant `nix-info` module, and all support for
legacy `nix.profile` option.
