System path fails to build when switching to a configuration

[pimeys]

Describe the bug

Switching to a configuration has been broken a couple of last commits on nixos unstable.

Steps To Reproduce

Steps to reproduce the behavior:

1. sudo nixos-rebuild switch

Result

warning: The interpretation of store paths arguments ending in `.drv` recently changed. If this command is now failing try again with '/nix/store/lvln9vwhlhwv7w4kf5yqvh452c6781bz-system-path.drv^*'
created 49831 symlinks in user environment
install-info: No such file or directory for gzip -d

Expected behavior

A switch should succeed and install the new configuration.

Additional context

Failing configuration: https://git.sr.ht/~pimeys/nixos/

Test if it's from https://search.nixos.org/options?channel=unstable&show=documentation.enable&from=0&size=50&sort=relevance&type=packages&query=documentation.enable

nixpkgs/nixos/modules/misc/documentation.nix

@Artturin Yep. Without manpages both of my systems build successfully. I can live with this for now, but I'm sure going to miss my man configuration.nix...

Debug by adding

set -x
set +x
Above and below those lines

For example by replacing the module https://wiki.nixos.org/wiki/Nixpkgs/Reviewing_changes#Modules (does not have to use fetchers, can use local paths)

I'm not sure what happened, but it seems to build right now. What I did is I fixed another issue in here:

#350030

And the docs seem to build correctly.
