`master` build is broken - but builds locally?

This is bizarre:

gebaar-libinput's source hasn't changed, rev hasn't changed, hash hasn't changed.

Did GitHub change something on their runner, and maybe gebaar-libinput exposes some FS quirk? (I think that's happened before with certain archives and macos targets for example)

Well... if I invalidate the (rev and update to redo the) hash, the hash does change:

   rev = "6ce14eb64a9f4bb8201bae26052521ae5e64f553";
-  sha256 = "sha256-NwF9TOJ6SzJJBa7mrUOCLEhz2xf0it7rVuOzhqvDwt0=";
+  sha256 = "sha256-9l59FrRUWM6L5dnZm5X/ir/X+ZgzQ2TT5TnNeX1OyIw=";

Is this related to nixpkgs's derivation having "fetchSubmodules" for their src?

[colemickens]

yup, that's it, and that's why it doesn't build with the updated hash.

fixed in #360
