Hi Sarah,

here's updated patch with your tips.

David, the way I test new packages is either by running:
[1]
guix shell --check --pure -D guix

or 
[2]
guix build -L <load_path>

+stores a database of previously authorized devices and will, depending on the
+policy set for the individual devices, automatically authorize newly connected
+devices without user interaction.
+
+The command-line utility @command{boltctl} manages Thunderbolt devices via
+@command{boltd}.  It can list devices, monitor changes, and initiate
+authorization of devices.")
