No, it does nothing remotely.  The manual has an example showing how to
use it over SSH, but it=E2=80=99s just an example...

... and it has a discussion of bandwidth efficiency and --missing.

That=E2=80=99s possible, by passing =E2=80=98guix archive=E2=80=99 the list=
 of profiles.

Even those not linked?  What for?  :-)

My reading of this is different: we need more/better tools to transfer
whole subsets of a store among different machines (remember we already
have =E2=80=98guix publish=E2=80=99 and =E2=80=98guix offload=E2=80=99 in t=
hat area.)

Once we have those, I think you may stop worrying about the database.  :-)

WDYT?
