While I personally don't like that we can't easily use
pushDownProperties from the module system and need to rely on internals,
we *already* use internals for the mkOverride case, so adding another
case for mkIf doesn't add a hard-to-find indirection.
I'm merging this, since this fixes a valid use case and it shouldn't
make refactoring worse than before.
The NixOS 21.03 release has been delayed to 21.05. See NixOS/rfcs#80.
There are two instances of 21.03 which have been left as is, since they
are in stateVersion comparisons. This will ensure that existing user
configurations which refer to 21.03 will continue to work.
`unitOption` is only used inside of `attrsOf` wich is perfectly capable of
handling the attrsets from `mkIf`, though the checkUnitConfig test
forbids it. This commit weakens that restriction to allow the usage of
`mkIf` inside of `systemd.services.<name>.serviceConfig.<something>`
etc.
Account for the fact that, when creating a lua package without the
"withPackages" helper, we dont get an extra "lua" attribute in the
package.
Therefore we need to distinguish between the "withPackages" case and the
direct ( or "empty" ) lua package.
For example with this nixos config:
```nix
{
services.httpd = {
enable = true;
package = pkgs.apacheHttpd.override {
luaSupport = true;
lua5 = pkgs.lua5_3.withPackages (ps: with ps; [ luafilesystem ] );
};
};
}
```
Here we say that we want to have apache to use a lua, packaged with the
`luafilesystem` module so that we can `require` that in scripts to
render http responses. There, the set that gets assigned to `lua5 ` does
not have a `luaversion` attribute, rather it has a `lua` attribute
wherein lies a `luaversion` attribute. If we dont package additional
modules, then we dont have that `lua` attribute in between and rather
directly have to use `luaversion` directly.
