The configured sysconfdir is used to look for nix.conf, so it needs
to be /etc, and not $out/etc, so we separate out the place where shell
profile files are installed, which is the only other place sysconfdir is
at all used.
See lix-project/lix#231 (comment)
for more info.

Functional tests can be run with
`meson test -C build --suite installcheck`.
Notably, functional tests must be run *after* running `meson install`
(Lix's derivation runs the installcheck suite in installCheckPhase so it
does this correctly), due to some quirks between Meson and the testing
system.
As far as I can tell the functional tests are meant to be run after
installing anyway, but unfortunately I can't transparently make
`meson test --suite installcheck` depend on the install targets.
The script that runs the functional tests, meson/run-test.py, checks
that `meson install` has happened and fails fast with a (hopefully)
helpful error message if any of the functional tests are run before
installing.

For brand new installations, neither NIX_LINK_NEW
(`$XDG_STATE_HOME/nix/profile` or `~/.local/state/nix/profile`), nor
NIX_LINK (`~/.nix-profile`) will exist.
This restores functionality to nix-env, which is relied upon by GitHub
Actions such as https://github.com/cachix/cachix-action and the Nixpkgs
EditorConfig (and other) CI.
One of our CI machines installs Nix via the official script and then
sources the nix-profile.sh script to setup the environment. However, it
doesn't have XDG_STATE_HOME set, which causes sourcing the script to
fail.
XDG Base Directory is a standard for locations for storing various
files. Nix has a few files which seem to fit in the standard, but
currently use a custom location directly in the user's ~, polluting
it:
- ~/.nix-profile
- ~/.nix-defexpr
- ~/.nix-channels
This commit adds a config option (use-xdg-base-directories) to follow
the XDG spec and instead use the following locations:
- $XDG_STATE_HOME/nix/profile
- $XDG_STATE_HOME/nix/defexpr
- $XDG_STATE_HOME/nix/channels
If $XDG_STATE_HOME is not set, it is assumed to be ~/.local/state.

Among all the characters that are allowed in a URL, both the percentage
sign "%" and the single quotation mark "'" needs escaping when written
as a environment variable in a systemd service file. While the single
quotation mark may be rare, the percentage sign is widely used to escape
characters in a URL. This is especially common in proxy setting, where
username and password may contain special characters that need
percentage escaping. This patch applies the following replacements:
% -> %%
' -> \'
The `fish_add_path` function is only available for fish 3.2.0 or newer,
and not on older versions.
This commit adds an alternative way to update the PATH when
`fish_add_path` does not exist.
being too specific about it requires more maintenance (or otherwise
produced more confusion and churn), since these points of contact change
over time.
Previously the MANPATH was set even if MANPATH was empty beforehand
which resulted in a MANPATH of only ~/.nix-profile/share/man which
omitted the default man page directory (commonly /opt/local/share/man)
from man page results.
Older versions of Fish (such as those bundled with Ubuntu LTS 22.04) do
not support return outside of functions. We need to use the equivalent
exit instead.
Before this patch, installing Nix using the Fish shell did not
work because Fish wasn't configured to add Nix to the PATH. Some
options in #1512 offered workarounds, but they typically involve
extra plugins or packages.
This patch adds native, out-of-the-box support for the Fish shell.
Note that Fish supports a `conf.d` directory, which is intended
for exactly use cases like this: software projects distributing
shell snippets. This patch takes advantage of it. The installer
doesn't append any Nix loader behavior to any Fish config file.
Because of that, the uninstall process is smooth and a reinstall
obliterates the existing nix.fish files that we place instead of
bothering the user with a backup / manual removal.
Both single-user and multi-user cases are covered. It has been
tested on Ubuntu, and a Mac with MacPorts, homebrew, and the
Fish installer pkg.
Closes#1512

A [recent-ish change](https://github.com/NixOS/nix/pull/6676) logs a warning when a potentially counterintuitive situation happens.
This now causes the multi-user installer to [emit a warning](https://github.com/NixOS/nixpkgs/issues/189043) when it's doing
the "seed the Nix database" step via a low-level `nix-store --load-db` invocation.
`nix-store` functionality implementations don't actually use profiles or channels or homedir as far as i can tell. So why are we
hitting this code at all?
Well, the current command approach for functionality here builds a [fat `nix` binary](https://github.com/NixOS/nix/blob/master/src/nix/local.mk#L23-L26) which has _all_ the functionality of
previous individual binaries (nix-env, nix-store, etc) bundled in, then [uses the invocation name](https://github.com/NixOS/nix/blob/master/src/nix/main.cc#L274-L277) to select the
set of commands to expose. `nix` itself has this behavior, even when just trying to parse the (sub)command and arguments:
```
dave @ davembp2
$ nix
error: no subcommand specified
Try 'nix --help' for more information.
dave @ davembp2
$ sudo nix
warning: $HOME ('/Users/dave') is not owned by you, falling back to the one defined in the 'passwd' file
error: no subcommand specified
Try 'nix --help' for more information.
dave @ davembp2
$ HOME=~root sudo nix
error: no subcommand specified
Try 'nix --help' for more information.
```
This behavior can also be seen pretty easily with an arbitrary `nix-store` invocation:
```
dave @ davembp2
$ nix-store --realize
dave @ davembp2
$ sudo nix-store --realize # what installer is doing now
warning: $HOME ('/Users/dave') is not owned by you, falling back to the one defined in the 'passwd' file
dave @ davembp2
$ sudo HOME=~root nix-store --realize # what this PR effectively does
dave @ davembp2
$
```
User on Matrix reported install problems which presented as
"vifs:editing error" which we traced back to vim griping about an
existing swap file. When opened interactively, it did this:
