As discussed earlier on the list, it would be nice™ to see why these
images are so big and what can be done about it.  Really, 1 GiB is
already a lot for such a small image.

In commit 040ae1881952c90dae9478e5cfff6aad0ce950da, I ended up
increasing the image size for the tests, which is not great IMO.  I
looked at ‘guix size’ and couldn’t find any obvious way to improve
things.

One problem with the installation OS is that it’s pulling ALSA and all
sorts of sound-related libraries (libsamplerate, etc.), which clearly is
unnecessary in the installation image.  That comes from the alsa-utils
udev rules.  We could remove those udev rules, but since they’re in
%base-services, I chose not to do that to avoid breaking everyone’s
config.

Food for thought!
