As of commit fce225471128c4a5246342b3aa1b7e53a8066211, ‘guix system
vm-image bare-bones.tmpl’ runs in ~2m42s on my SSD-based laptop.  The
key commits here are fce225471128c4a5246342b3aa1b7e53a8066211 and
bb3b6ccb05550fbfbeb459c68819a752327d6e1e.

Regarding deduplication (commit
b5460d95e970608bee7a794590be1b051b57d3a3), I found that it doesn’t
change the image size of bare-bones.tmpl (1.2G), but enabling it makes
things slower, ~6m.

Lemme know how it goes for you!

Thanks,
Ludo’.
