* manual: Contributing -> Development, Hacking -> Building
what's currently called "hacking" are really instructions for setting up
a development environment and compiling from source. we have
a contribution guide in the repo (which rightly focuses on GitHub
workflows), and the material in the manual is more about working
on the code itself.
since we'd otherwise have three headings that amount to "Building Nix",
this change also moves the "classic Nix" instructions to the top.
we may want to reorganise this in the future, and bring
contributor-oriented information closer to the code, but for now let's
stick to more accurate names to ease navigation.
Different parts of the project honor different sets of proxy environment
variables. With this commit all parts of the project will honor the same
set of proxy environment variables.

* move single-user uninstall to the end
this is not the default method of installation, and therefore irrelevant
for most users.
* move the backup restore instructions to the first step
for most users we can expect that the system-wide shell init files were
not ever touched, so we can as well tell them to do the most likely
thing.
from experience, while it's not necessarily safe to just mess with these
files, most people are simply confused by the complexity of
instructions.
* provide more detailed instructions for using `sudo vifs`
we can expect most beginners not to ever have used `vi`, and they will
probably need some hand-holding.
* express instructions as a script

channels make everything more stateful, and therefore more complicated
and potentially confusing, but aren't needed for this task, so don't encourage their use.
* deduplicate installation instructions
- reorder sections to present pinned installation more prominently
- remove outdated notes on the macOS installer rework
- update instructions to handle the installer tarball

It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:
- unit tests depending on building, functional tests don't (e.g. when
we test already-built Nix)
- unit tests can be installed, functional tests cannot
- unit tests neeed extra libraries (GTest, RapidCheck), functional
tests need extra executables (jq).
- unit tests are run by `make check`, functional tests are run by `make
installcheck`
Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.
I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

* docker: publish images to ghcr.io
docker.com announced their intention to remove the free plan used by
OSS. The nixos/nix image is essential to various CI runs to build with
nix. To provide a continuity plan, this commit pushes the image to
ghcr.io as well.

For people working on Nix with `nix develop`, it's better to just use
`autoreconfPhase` and `configurePhase`, which is standard Nixpkgs / nix
shell make from Nixpkgs practice --- it is good to emphasize the degree
to which Nix is *just* a regular C++ project which can be worked on in
the regular way.
(For people running `nix-shell`, the story is similar, except
`configurePhase` would use non-writable store paths, which matters for
hte times we use output paths before `make install`, so I kept the
existing `./configure ...` instruction.)
For people building Nix without Nix (e.g. packaging it for another
distro) they also don't need `bootstrap.sh`, and can just run
`autoreconf -vfi` directly. (More likely, they have their own idioms to
do this just as we have `autoreconfPhase`.)
e.g. nix-env -e subversion => nix-env --uninstall subversion
The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.
The change was made with the following script:
<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>
and sanity checked visually.
`/etc/bash.bashrc` is backed up as `/etc/bash.bashrc.backup-before-nix`,
but since other changes might have been introduced in the meantime we can't
just tell the user to revert.
placed in a subsection of the binary install, the instructions are hard
to find. putting them in a separate page that is shown in the table of
contents should make it easier for users to find what they need when
they need it.
This provides a platform-independent way to configure the SSL
certificates file in the Nix daemon. Previously we provided
instructions for overriding the environment variable in launchd, but
that obviously doesn't work with systemd. Now we can just tell users
to add
ssl-cert-file = /etc/ssl/my-certificate-bundle.crt
to their nix.conf.
Before #5150 the copy-to-store phase of the install was idempotent,
but the recursive cp isn't. This is probably baiting a few people
into trying corrective installs that will fail.
The uninstall instructions used to accidentally remove the nix-darwin
LaunchDaemon, this was dropped. However, the original intent was to
remove the Store volume mounting LaunchDaemon.
