Make sure that people who run Nix in non-interactive mode (and so don't have the possibility to interactively accept the individual flake configuration settings) are aware of this flag.
Fix#7086
These settings seem harmless, they control the same polling
functionality that timeout does, but with different behavior. Should
be safe for untrusted users to pass in.
I just had a colleague get confused by the previous phrase for good
reason. "valid" sounds like an *objective* criterion, e.g. and *invalid
signature* would be one that would be trusted by no one, e.g. because it
misformatted or something.
What is actually going is that there might be a signature which is
perfectly valid to *someone else*, but not to the user, because they
don't trust the corresponding public key. This is a *subjective*
criterion, because it depends on the arbitrary and personal choice of
which public keys to trust.
I therefore think "trustworthy" is a better adjective to use. Whether
something is worthy of trust is clearly subjective, and then "trust"
within that word nicely evokes `trusted-public-keys` and friends.
The history is not critical to the functionality of nix repl, so it's
enough to warn here, rather than refuse to start if the directory Nix
thinks the history should live in can't be created.
- call close explicitly in writeFile to prevent the close exception
from being ignored
- fsync after writing schema file to flush data to disk
- fsync schema file parent to flush metadata to disk

Remove the `verify TLS: Nix CA file = 'blah'` message that Nix used to print when fetching anything as it's both useless (`libcurl` prints the same info in its logs) and misleading (gives the impression that a new TLS connection is being established which might not be the case because of multiplexing. See #7011 )
Mainly:
- Try to triangulate between narrative that framed this as
a new/easy process and the need for a reference that will
not quickly grow stale.
- Fix a ~continuity issue where the text was talking about
"your Cachix cache" before saying that you'd need to make
a Cachix cache to enable the installer tests.
- Adopt suggestion on titling, and nest subtitles in the
installer test section.
This commit adds an optional `__impure` parameter to fetchurl.nix, which allows
the caller to use `libfetcher`'s fetcher in an impure derivation. This allows
nixpkgs' patch-normalizing fetcher (fetchpatch) to be rewritten to use nix's
internal fetchurl, thereby eliminating the awkward "you can't use fetchpatch
here" banners scattered all over the place.
