Take two of #40708 (4fe2898608).
That PR attempted to bidirectionally default `config.nixpkgs.system` and
`config.nixpkgs.localSystem.system` to each be updated by the other. But
this is not possible with the way the module system works. Divergence in
certain cases in inevitable.
This PR is more conservative and just has `system` default `localSystem`
and `localSystem` make the final call as-is. This solves a number of
issues.
- `localSystem` completely overrides `system`, just like with nixpkgs
proper. There is no need to specify `localSystem.system` to clobber the
old system.
- `config.nixpkgs.localSystem` is exactly what is passed to nixpkgs. No
spooky steps.
- `config.nixpkgs.localSystem` is elaborated just as nixpkgs would so
that all attributes are available, not just the ones the user
specified.
The remaining issue is just that `config.nixpkgs.system` doesn't update
based on `config.nixpkgs.localSystem.system`. It should never be
referred to lest it is a bogus stale value because
`config.nixpkgs.localSystem` overwrites it.
Fixes#46320
- based on module originally written by @srhb
- complies with available options in cfssl v1.3.2
- uid and gid 299 reserved in ids.nix
- added simple nixos test case
This reverts commit 095fe5b43d.
Pointless renames considered harmful. All they do is force people to
spend extra work updating their configs for no benefit, and hindering
the ability to switch between unstable and stable versions of NixOS.
Like, what was the value of having the "nixos." there? I mean, by
definition anything in a NixOS module has something to do with NixOS...
My c6f7d43678 made the mistake of not
having enough defaults. Now both variables are default as the *explicit*
value of the other, or a fallback. The fallback of `system` is the
default of `localSystem.system`. The fallback of `localSystem` is not
the other default (projected), as that would cause a cycle, but `{
system = builtins.currentTime; }` just as nixpkgs itself does it.
lib.optional returns a singleton or an empty list. Therefore the
argument does not need to be wrapped in a list.
An alternative patch could have used lib.optionals but seems like no
more elements are going to be added to the optional list.
As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:
* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`
As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.
I know that "devinfo" output does not currently exist, but so does "devman".
It is mentioned in the nixpkgs manual, but no derivation in nixpkgs actually uses it.
a) Some providers can update multiple domains - support that.
b) Make "zone" and "script" configurable. Some providers require these.
c) Instead of leaving the ddclient daemon running all the time, use a systemd
timer to kick it off.
d) Don't use a predefined user - run everything via DynamicUser
e) Add documentation
- `localSystem` is added, it strictly supercedes system
- `crossSystem`'s description mentions `localSystem` (and vice versa).
- No more weird special casing I don't even understand

This fixes the `update-locatedb` service when using the `mlocate`
package.
The service as-is does not properly handle flags during update of the
relevant database when configured to use the `mlocate` package.
The man entry for `updatedb` associated with `mlocate` does not say
that it supports environment variables in place of command line flags,
whereas the `findutils` package's updatedb does so.
To support this distinction, we pass the relevant settings as flags to
the `updatedb` program when using the `mlocate` package.
Fixes#29279
We should be able to deploy a NixOS 18.03 system with the current nixops
stable release. Some options were renamed, so instead of
`mkRenamedOptionModule` we introduce them as read-only interal options
that won't be rendered in the manual.
Only the options that are needed to make nixops evaluations succeed were
added.
This commit should probably be reverted after or before the 18.09 release,
depending on the nixops 1.6 release.
The user will not get the warning that these have been renamed but
this change is mentioned in the release notes.
Fixes#34253.
