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.
Added using the following sed scripts:
- For command-ref/opt-common.md:
s~- `(--?)([^`]+)`~- [`\1\2`]{#opt-\2}~g
- For expressions/builtin-constants.md:
s~- `(builtins\.?)([^`]+)`~- [`\1\2`]{#builtins-\2}~g
- For expressions/advanced-attributes.md
s~^ - `([^`]+)`~ - [`\1`]{#adv-attr-\1}~g
and manually adjusted outputHashAlgo & outputHashMode.
- For glossary.md
s~^ - (`([^`]+)`|(.+)) ?\\~ - [\1]{#gloss-\2\3}\\~g;
s~(gloss-\w+) ~\1-~g
and manually adjusted anchors for Nix expression, user environment, NAR, ∅ and ε.
- For command-ref/env-common.md
s~^ - `([^`]+)`~ - [`\1`]{#env-\1}~g'
Add a new `file` fetcher type, which will fetch a plain file over
http(s), or from the local file.
Because plain `http(s)://` or `file://` urls can already correspond to
`tarball` inputs (if the path ends-up with a know archive extension),
the URL parsing logic is a bit convuluted in that:
- {http,https,file}:// urls will be interpreted as either a tarball or a
file input, depending on the extensions of the path part (so
`https://foo.com/bar` will be a `file` input and
`https://foo.com/bar.tar.gz` as a `tarball` input)
- `file+{something}://` urls will be interpreted as `file` urls (with
the `file+` part removed)
- `tarball+{something}://` urls will be interpreted as `tarball` urls (with
the `tarball+` part removed)

The produced path is then allowed be imported or utilized elsewhere:
```
assert (43 == import (builtins.toFile "source" "43")); "good"
```
This will still fail on write-only stores.

This adds a new command, :bl, which works like :b but also creates
a GC root symlink to the various derivation outputs.

Welcome to Nix 2.6.0. Type :? for help.
nix-repl> :l <nixpkgs>
Added 16118 variables.
nix-repl> :b runCommand "hello" {} "echo hi > $out"
This derivation produced the following outputs:
./repl-result-out -> /nix/store/kidqq2acdpi05c4a9mlbg2baikmzik44-hello
[1 built, 0.0 MiB DL]
ckie@cookiemonster ~/git/nix -> cat ./repl-result-out
hi
gives 2-5% performance improvement across a board of tests.
LTO is broken when using clang; some libs link fine while others crash
the linker with a segfault in the llvm linker plugin. 🙁
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.
Clarify that `/nix` being present after the uninstall is normal and it
will only disappear after a reboot.

The multi-user installation on macOS, which is now the only option, has
gotten complicated enough that it discourages some users from checking
Nix out for fear of being left with a "dirty" system. Detailed
uninstallation instructions should make this less of an issue.
