That is confusing indeed.  It comes from the fact that =E2=80=98guix offloa=
d=E2=80=99 in
the last case is running as root; thus, it sees a different
~/.ssh/config.

We could instruct =E2=80=98guix offload=E2=80=99 to always ignore ~/.ssh/co=
nfig, but
that wouldn=E2=80=99t be great because using it can be useful.

Perhaps it should emit a warning when not running as root?

Thanks,
Ludo=E2=80=99.
