WPSD Bookworm for Raspberry Pi Released

Today, I’ve released the long-awaited WPSD “Bookworm”-based disk image for the Raspberry Pi (“RPi”) platforms. This is the (only) WPSD disk image that supports the newer Raspberry Pi Model 5 platform.

Note that this new WPSD RPi Bookworm disk image is universal; so it will support other Raspberry Pi Platforms, not only the Raspberry Pi 5.

(We will release Bookworm-based WPSD disk images for all the other architectures/platforms, of which we provide existing “Bullseye”-based disk images, in the near future.)

NOTE: There are some major differences between this new Bookworm-based WPSD disk image/operating system, and the popular/existing “Bullseye”-based WPSD disk image(s); so please read the rest of this document to learn how to properly install the WPSD Bookworm software
