- Install a Debian filesystem using debootstrap on your NFS server (normal x86
  Linux machine, for example):

  $ debootstrap --arch=arm64 sid /home/pi

- Install qemu-aarch64 on host system and set up binfmt_misc to allow for
  chroot

  - depends on host system; Fedora and Arch have packages for this
  - no need to get arm64 libraries on host as the chroot will take care

How to install Fedora 32 on a Raspberry Pi 4 in 64-bit mode (aarch64 / ARM64
architecture):

- Put RPi4-UEFI firmware on the SD card: https://rpi4-uefi.dev/

  - The SD card by default has a FAT16 partition that is the RPi boot
    partition. Delete everything there and unzip an RPi4-UEFI release zip in
    the root. If starting from a blank SD card, create one partition (DOS
    partition table type), and format it as FAT16.

# OpenBSD dhcpcd configuration to get an IPv6 prefix delegation from a native-IPv6 ISP (e.g., Comcast).
#
# Here, 'axe0' is the interface connected to the cable modem, 'em0' is on the LAN.
# The configuration will ask for a /60, and will assign the /64 with subnet ID 1
# to em0.
# Use an IPv6 router advertisement daemon to advertise this to the rest of the network!

To set up a new server with a Gogs instance, similar to GitHub:

1. Create a clean VM with Debian (on e.g. Digital Ocean) and point a (sub)domain to it
2. Log in and change the SSH daemon to listen on port 2222
   - edit /etc/ssh/sshd_config, "Port 22" -> "Port 2222", systemctl restart ssh
   - log out; log in with "ssh -p 2222 root@..."
3. Install Docker
   - https://docs.docker.com/engine/installation/linux/debian/
4. Create data directories
   - mkdir /home/gogs
