This turns errors like:
error: flake output attribute 'hydraJobs' is not a derivation or path
into errors like:
error: expected flake output attribute 'hydraJobs' to be a derivation or
path but found a set: { binaryTarball = «thunk»; build = «thunk»; etc> }
This change affects all InstallableFlake commands.

* reword documentation on `nix-copy-closure`
- one sentence per line
- be more precise with respect to which Nix stores are being accessed
- make a clear distinction between store paths and store objects
- add links to definitions of terms
- clarify which machine is which
- --to and --from don't take arguments

The JSON format no longer uses the legacy ATerm `r:` prefixing nonsese,
but separate fields.

- add links to definitions of terms
- one sentence per line
- be more specific about which store is used for the import
- clearly distinguish store paths and store objects
- make a recommendation to use `nix-copy-closure` for efficient SSH transfers
Basically I'd expect the same behavior as with `nix-build`, i.e.
with `--keep-going` the hash-mismatch error of each failing
fixed-output derivation is shown.
The approach is derived from `Store::buildPaths` (`entry-point.cc`):
instead of throwing the first build-result, check if there are any build
errors and if so, display all of them and throw after that.
Unfortunately, the BuildResult struct doesn't have an `ErrorInfo`
(there's a FIXME for that at least), so I have to construct my own here.
This is a rather cheap bugfix and I decided against touching too many
parts of libstore for that (also I don't know if that's in line with the
ongoing refactoring work).

given `nix-copy-closure` exists, it doesn't make much sense to do
nix-store --export $paths | nix-store --import --store ssh://foo@bar
since that dumps everything rather than granularly transferring store
objects as needed.
therefore, pick an example where dumping the entire closure into a file
actually makes a difference, such as when deploying to airgapped systems.
In addition:
- Take the opportunity to add a bunch more missing hyperlinks, too.
- Remove some glossary entries that are now subsumed by dedicated pages.
We used to not be able to do this without breaking link fragments, but
now we can, so pick up where we left off.

the individual commands' documentation should provide enough examples to
make sense of the options and judge what to use and when. proper guides,
which would require a more elaborate setup to show off Nix's
capabilities are out of scope for the reference manual.
* doc: convention improvements for copying closure
use -P, which only considers executables but not shell builtins

pararameterisation is not actually needed the way things are currently
set up, and it confused me when trying to understand what the code does.
all but one test sources vars-and-functions.sh, which nominally only
defines variables, but in practice is always coupled with the actual
initialisation. while the cleaner way of making this more legible would
be to source variables and initialisation separately, this would produce
a huge diff.
the change requires a few small fixes to keep the tests working:
- only create test home directory during initialisation
that vars-and-functions.sh wrote to the file system seems not write
- fix creation of the test directory
due to statefulness, the test home directory was implicitly creating
the test root, too. decoupling that made it apparent that this was
probably not intentional, and certainly confusing.
- only source vars-and-functions.sh if init.sh is not needed
there is one test case that only needs a helper function but no
initialisation side effects
- remove some unnecessary cleanups and split parts of re-used test code
there were confusing bits in how initialisation code was repurposed,
which break if trying to refactor the outer layers naively...
* Document string context
Now what we have enough primops, we can document how string contexts
work.

When trying the „nix-store info“ commands on this page I received the error "error: 'info' is not a recognised command". According to https://github.com/NixOS/nix/issues/9349 info seems to have been an alias for ping. So why not just replace info with ping?
* 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

I've added the new local.mk to the package sources. While this
should not be needed for the build, it is the simplest solution,
and won't cause many extra rebuilds, because the file won't change
very often.
Now that we have a few things identifying content address methods by
name, we should be consistent about it.
Move up the `parseHashAlgoOpt` for tidiness too.
Discussed this change for consistency's sake as part of #8876

This requires `--substitute-on-destination` if you want the remote side
to substitute instead of copying if possible.
For completeness sake, document it here.
Also, the stable Nix from nixpkgs is still 2.18, so more folks may
stumble upon this when this is bumped, so I'd expect this to be actually
useful.
Closes#10182
* show Nix logo in the manual
the location of files is hard-coded by mdBook.
there is also seems to be no way to define custom templates, therefore
all styling has to be done in the CSS override.

I was using by mistake the .#nix-clangStdenv shell to retrieve clangd.
This clangd is unusable with the project and constantly segfaults.
Let's explicitly state which shell the user should use in the docs.
I don't really understand the source of this segfault. I assume it's
related to a clang version incompatibility. (16.0.6 for
.#nix-clangStdenv 14.0.6 for .#native-clangStdenvPackages)
- Align the “frequent” release cycle with the calendar
- The 6-month release cycle is hard to keep track of. A monthly
release will make it much easier to remember the release date.
- Officialise the support for a stable version maintained for as long as NixOS stable
- This is already the case in practice, it just happens that the
“stable” Nixpkgs version is whichever version was deemed
stable-enough at the time of the NixOS release.
Officialise that by cutting a new major release alongside each NixOS one.
Note that this breaks whatever semver compatibility Nix might pretend to
have, but I don't think it makes sense any way.
previously we reported the error at the beginning of the binding
block (for plain inherits) or the beginning of the attr list (for
inherit-from), effectively hiding where exactly the error happened.
this also carries over to runtime positions of attributes in sets as
reported by unsafeGetAttrPos. we're not worried about this changing
observable eval behavior because it *is* marked unsafe, and the new
behavior is much more useful.
we already normalize attr order to lexicographic, doing the same for
formals makes sense. doubly so because the order of formals would
otherwise depend on the context of the expression, which is not quite as
useful as one might expect.

desugaring inherit-from to syntactic duplication of the source expr also
duplicates side effects of the source expr (such as trace calls) and
expensive computations (such as derivationStrict).
- move all reference documentation to the `builders` configuration setting
- reword documentation on machine specification, add examples
- disable showing the default value, as it rendered as `@/dummy/machines`, which is wrong
- highlight the examples
- link to the configuration docs for distributed builds
- builder -> build machine

the interesting information is on the proper pages, and is now presented
a bit more prominently.
the paragraph was a bit confusing to read, also because an anchor link
to an inline definition was in the middle of the sentence. "local store"
now has its own glossary entry.
