+Flakes
+------
+
+Due to a bug in nix build, flakes that refer to relative path (input
+type "path") don't work when called via an url (nix build git+ssh://some-url).
+Relative paths (except in "flakes/private") should be renamed to
+git+https urls ideally. E.g.:
+```
+    inputs.libspf2 = {
+-    path = "../libspf2";
+-    type = "path";
++    url = "https://git.immae.eu/perso/Immae/Config/Nix.git";
++    type = "git";
++    dir = "flakes/libspf2";
+    };
+```
