The old trigger would actually never cause a restart since the path
doesn't change. With this change the trigger is now using the actual
configuration path in the Nix store, which depends on the content.
(cherry picked from commit 65700a4fd1)
This option provides a more convenient way to overlay dummy packages.
It also adds a function `config.lib.test.mkStubPackage` that can,
e.g., be used for `package` options.
Polybar's config format is a bit strange, and lists in particular are
annoying to handle. This enables using normal nix lists and nested
attrsets instead.
This change is not backwards-compatible, because the INI converter
converts lists of strings to space-separated values, and this does
something else. I expect that this is only relevant for the
`modules-left` etc bar setting, but that's enough to break things :(.
