This is great!

Thank you for the instructions.  I thought I had all keys, but
apparently at least one of them is missing.  “make authenticate” fails
for me with this error:

Throw to key `srfi-34' with args `(#<condition &message [message: "could not 
authenticate commit b291c9570d5a27b11472df3df61cef9ed012241b: key 
B943509D633E80DD27FC4EED634A8DFFD3F631DF is missing"] 7f70fb08c240>)'.

I previously downloaded the gpg keyring from Savannah:

    https://savannah.gnu.org/project/memberlist-gpgkeys.php?group=guix

Looks like Hartmut used to use a different key, which I don’t have.
