How can I reference the escapeSystemdPath function (from nixpkgs' nixos/lib/utils.nix) in my config? (lemmy.ml)

I want to call the escapeSystemdPath (defined in nixpgs at nixos/lib/utils.nix) to derive the name of a systemd mount unit from the target path (eg. srv-my-dir.mount from /srv/my/dir), but I can't figure out how I can reference it... any ideas?

Probably nixpkgs.lib.escapeSystemdPath. If you are talking about a NixOS config you can request lib as an argument.

(I haven't actually checked, but this is where most lib functions are)

It's not on lib, it's on utils, which is not necessarily exposed all that well. You should be able to just get it passed into your module config, eg.

{config, pkgs, lib, utils, ...}: { # do your thing }
