This replaces some derivation outputs by simple strings rather than
full Nix store paths. This removes the need to download the whole
derivation when all we need is a static string.
(cherry picked from commit 797c77a00a)
This fixes a build error occurring when building a configuration
having fontconfig enabled and `home.packages` only containing one
package installing things to `/lib`.
Also adds a number of test cases to verify the fontconfig cache
generation functionality.
Fixes#703
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.
Fixes#659
