Allow access to the emergency shell
By default, the emergency shell prompts for the root password.  If the
root account is locked, the emergency shell is unusable.  This makes it
impossible to troubleshoot issues before the network is available.
Fortunately, systemd can be configured to skip the root password prompt
and allow access to the emergency shell with an environment variable.

Basement Hud Network-Booted OS

Customized Fedora-based operating system distributed as an immutable root filesystem image.

Building

Must run on a Fedora host or privileged container.

Build the root filesystem image:

make rootfs

This will create an _build/rootfs directory containing the root filesystem hierarchy. The _build/rootfs/boot directory contains the necessary files to boot the system:

  • efi: This directory contains the Raspberry Pi firmware files
  • initramfs.img: Early userspace image
  • vmlinuz: Kernel image
  • basementhud.squashfs: Root filesystem image

The Raspberry Pi firmware, initramfs image, and kernel image files must be served by a TFTP, while the rootfs image is served by NBD.

Build the initramfs image:

make initramfs
