I cloned guix git repository and tried make installation image, but get
errors.

$ git clone https://git.savannah.gnu.org/git/guix.git
...
$ cd guix
$ guix system disk-image --image-size=1G gnu/system/install.scm
guix system: error: failed to load 'gnu/system/install.scm':
ice-9/boot-9.scm:2870:6: In procedure resolve-interface:
ice-9/boot-9.scm:2870:6: no code for module (gnu packages bootloaders)

Why? I did everything like the Manual says.
