Eelco Dolstra 3c54e9ba01 Add 'nix flake archive' command
This copies a flake and all its inputs recursively to a store (e.g. a
binary cache). This is intended to enable long-term reproducibility
for flakes. However this will also require #3253.

Example:

  $ nix flake archive --json --to file:///tmp/my-cache nixops
  {"path":"/nix/store/272igzkgl1gdzmabsjvb2kb2zqbphb3p-source","inputs":{"nixops-aws":{"path":"/nix/store/ybcykw13gr7iq1pzg18iyibbcv8k9q1v-source","inputs":{}},"nixops-hetzner":{"path":"/nix/store/6yn0205x3nz55w8ms3335p2841javz2d-source","inputs":{}},"nixpkgs":{"path":"/nix/store/li3lkr2ajrzphqqz3jj2avndnyd3i5lc-source","inputs":{}}}}

  $ ll /tmp/my-cache

Eelco Dolstra b9fb372075 Add --update-input flag to update a specific flake input
Typical usage:

  $ nix flake update ~/Misc/eelco-configurations/hagbard --update-input nixpkgs

to update the 'nixpkgs' input of a flake while leaving every other
input unchanged.

The argument is an input path, so you can do e.g. '--update-input
dwarffs/nixpkgs' to update an input of an input.

Fixes #2928.

Not that it matters a lot anymore - we respect lock files of inputs
now, so we're doing a lot fewer flake lookups.

Eelco Dolstra 26f895a26d Clean up the lock file handling flags
Added a flag --no-update-lock-file to barf if the lock file needs any
changes. This is useful for CI systems if you're building a
checkout. Fixes #2947.

Renamed --no-save-lock-file to --no-write-lock-file. It is now a fatal
error if the lock file needs changes but --no-write-lock-file is not
given.

Eelco Dolstra f68bed7f67 Add flag --override-input to override specific lock file entries
E.g.

  $ nix flake update ~/Misc/eelco-configurations/hagbard \
    --override-input 'dwarffs/nixpkgs' ../my-nixpkgs

overrides the 'nixpkgs' input of the 'dwarffs' input of the top-level
flake.

Fixes #2837.

Eelco Dolstra cc22cf662b Respect lock files of inputs + fine-grained lock file control
When computing a lock file, we now respect the lock files of flake
inputs. This is important for usability / reproducibility. For
example, the 'nixops' flake depends on the 'nixops-aws' and
'nixops-hetzner' repositories. So when the 'nixops' flake is used in
another flake, we want the versions of 'nixops-aws' and
'nixops-hetzner' locked by the the 'nixops' flake because those
presumably have been tested.

This can lead to a proliferation of versions of flakes like 'nixpkgs'
(since every flake's lock file could depend on a different version of
'nixpkgs'). This is not a major issue when using Nixpkgs overlays or
NixOS modules, since then the top-level flake composes those
overlays/modules into *its* version of Nixpkgs and all other versions
are ignored. Lock file computation has been made a bit more lazy so it
won't try to fetch all those versions of 'nixpkgs'.

However, in case it's necessary to minimize flake versions, there now
are two input attributes that allow this. First, you can copy an input
from another flake, as follows:

  inputs.nixpkgs.follows = "dwarffs/nixpkgs";

This states that the calling flake's 'nixpkgs' input shall be the same
as the 'nixpkgs' input of the 'dwarffs' input.

Second, you can override inputs of inputs:

  inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;
  inputs.nixops.inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;

or equivalently, using 'follows':

  inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;
  inputs.nixops.inputs.nixpkgs.follows = "nixpkgs";

This states that the 'nixpkgs' input of the 'nixops' input shall be
the same as the calling flake's 'nixpkgs' input.

Finally, at '-v' Nix now prints the changes to the lock file, e.g.

  $ nix flake update ~/Misc/eelco-configurations/hagbard
  inputs of flake 'git+file:///home/eelco/Misc/eelco-configurations?subdir=hagbard' changed:
    updated 'nixpkgs': 'github:edolstra/nixpkgs/7845bf5f4b3013df1cf036e9c9c3a55a30331db9' -> 'github:edolstra/nixpkgs/03f3def66a104a221aac8b751eeb7075374848fd'
    removed 'nixops'
    removed 'nixops/nixops-aws'
    removed 'nixops/nixops-hetzner'
    removed 'nixops/nixpkgs'

structured-attrs: chown .attrs.* files to builder
Otherwise `chmod .`'ing the build directory doesn't work anymore, which
is done in nixpkgs if sourceRoot is set to '.'.

Benjamin Hipple 5d24e18e29 doc: touchup release notes for 2.3
- At the top of the release notes, we announce sandboxing is now enabled by default,
then at the bottom it says it's now disabled when missing kernel support. These
can be merged into one point for clarity.

- The point about `max-jobs` defaulting to 1 appears unrelated to sandboxing.
