+[2025-01-22 Wed] ... actually, this ran into some issues with the certificate, so I'm just going to do a reinstall.

+Previous notes
+
+1. Create a Nanode.
+2. Update the DNS for bbb.emacsverse.org with its IP address. (dns.he.net)
+3. Reboot into Rescue mode. In Lish:
+   #+begin_src sh :eval  no
+   passwd  # set interactively
+   sed -i -e 's/#PasswordAuthentication yes/PasswordAuthentication yes/g' /etc/ssh/sshd_config
+   echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config
+   service ssh start
+   #+end_src
+4. From the backup directory:
+   gunzip -c bbb-img-2024-12-08.img.gz | ssh root@bbb.emacsconf.org "dd of=/dev/sda bs=4M status=progress oflag=direct iflag=fullblock"
+5. After I resized to 4core 8GB RAM, I couldn't log in with SSH, so I used the Linode shell. ~sshd -t~ said no host keys available. Fix:
+   #+begin_src sh :eval no
+   ssh-keygen -A
+   service ssh --full-restart
+   #+end_src
+6. ./bbb-install.sh -v jammy-300 -s bbb.emacsverse.org -e emacsconf@sachachua.com
