What's this 'fd' and guix_db_prefix about?
If this is necessary, shouldn't it be documented in the main manual.

This "make authenticate" gives a false sense of security -- the MITM
attacker could have changed the Makefile.am to let the 'authenticate'
target be a no-op.  Likewise, authentication must happen before
./bootstrap and ./configure otherwise it's too late.

Also, didn't this authentication already happen in
