Marks Rpi Cluster continues to run 24/7. As before it is running Einstein BRP4 work, with the occasional Asteriods work unit as a resend. They seem to be out of work at the moment apart from the resends (work units that have failed to validate or have timed-out).
On Saturday the 10th of June Debian release their Bookworm release. Already the question haa been asked when we can expect Raspberry Pi OS to get updated. Raspberry Pi OS has the same 6.1 kernel as Debian Bookworm so I expect it will be "soon".
Pi Hole which is available for ARM64 and x64 machines doesn't work under Debian Bookworm, so they need to push an update. They normally support the current and one prior version back, so that means they would support Debian 11 (Bullseye) and Debian 12 (Bookworm).
