I pushed the four patches as 3270308eebe82075d2f02517c5a2b1599928495c.

Let me know if anything’s amiss!

Thanks,

There are two hosts running Guix.  The target host runs 
“guix-daemon” with “--listen=0.0.0.0:9999”; it does not listen on 
a local socket file.  Trying to copy store items to the target 
host fails with this backtrace:

The (guix ssh) appears to assume that the remote daemon listens on 
a socket file.  Telling the daemon to also listen on a socket file 
works around this problem<.
