At work we tend to keep our large code workspaces under a /scratch folder. Is there a NixOS option to declare such a folder/file should exist?

I know about environment.etc which will setup symlink from /etc into the nix store.

Otherwise I'd have to resort to declare some systemd boot-up script, doing mkdir -p and so on - which feels ugly.

I would probably use systemd.tmpfiles.rules. See its entry in docs, e.g. man configuration.nix.
