Add a home.uid option similar to home.username. When set, the
activation script verifies the current UID matches the expected
value using the new checkUid function.
When using the NixOS or nix-darwin modules, home.uid is
auto-discovered from users.users.<name>.uid when that value
is set.
This is useful for constructing paths that depend on the user's
UID, such as /run/user/<uid> paths for gpg-agent sockets or
other user-specific runtime directories.
`lib` comes from the Nixpkgs used to instantiate Home Manager itself and
cannot change within the module fixpoint. However, `pkgs` is configurable
(via `nixpkgs.*` or `_module.args`) and may come from a different Nixpkgs
instance from the one providing `lib`.
Mismatches between Home Manager's release and the release of the `pkgs`
instance are more common and also more likely to cause subtle issues.
This change extends the release check to include `pkgs.lib.trivial.release`
so that such mismatches can be detected and reported.
This commit introduces `home.sessionSearchVariables` option, that is
created to be a "generic" version of `home.sessionPath` for any
environment variables that is similar to PATH (e.g.: MANPATH). This
allows composition of those variables between multiple modules, avoiding
issues like this one:
https://github.com/nix-community/home-manager/pull/4579/files#r1364374048
This commit also reimplements `home.sessionPath` as terms of
`home.sessionSearchVariables`, to reduce code duplication and show that
the code is correct.
The behavior is to prepend the new search paths. This will allow
the user to override the defaults easily by setting it later in the
configuration.
Unfortunately, using `attrsOf` is not possible since it results in too
eager evaluation. In particular, the
home.sessionVariables = {
FOO = "Hello";
BAR = "${config.home.sessionVariables.FOO} World!";
};
example will cause an infinite recursion.
This commit restores the option type of
- `home.sessionVariables`,
- `pam.sessionVariables`,
- `programs.bash.sessionVariables`, and
- `programs.zsh.sessionVariables`
to `attrs`. It also adds test cases for the above options to avoid
regressions.
