An attribute set of lib overlays, they're similar to normal
|
|
[overlays](https://nixos.org/manual/nixpkgs/stable/#chap-overlays).
|
|
|
|
Note that the overlays themselves are not mergeable. While overlays
|
|
can be composed, the order of composition is significant, but the
|
|
module system does not guarantee sufficiently deterministic
|
|
definition ordering, across versions and when changing `imports`.
