Yes.  The issue is I cannot offload to a machine where I have an SSH
account and where Guix is installed if the sysadmin does not configure
correctly this /root/.ssh/.

This patch LGTM.  At least, it could save time for people configuring
offload. :-)

I am fine to close the issue but, as I said, the fix seems to be able to
offload without root access but just an SSH access.
