    # Snapcraft is only officially distributed as a snap, as is LXD. The socket

    ./lxd-socket-path.patch
    # In certain places, Snapcraft expects an /etc/os-release file to determine
    # host info which doesn't exist in our test environment. This is a
    # relatively naive patch which helps the test suite pass - without it *many*
    # of the tests fail. This patch will likely never be accepted upstream.
    ./os-platform.patch
    # Snapcraft will try to inject itself as a snap *from the host system* into
    # the build system. This patch short-circuits that logic and ensures that
    # Snapcraft is installed on the build system from the snap store - because
    # there is no snapd on NixOS hosts that can be used for the injection. This
    # patch will likely never be accepted upstream.
    ./set-channel-for-nix.patch
    # Certain paths (for extensions, schemas) are packaged in the snap by the
    # upstream, so the paths are well-known, except here where Snapcraft is
    # *not* in a snap, so this patch changes those paths to point to the correct
    # place in the Nix store. This patch will likely never be accepted upstream.
