Re: Raspberry Pi Zero: please use with a CPU cooler!

Now you confused me completely. IMHO 100% CPU means 100% busy: other tasks need to wait until they can be processed. The processor will run @ 1GHz (as fast as it can) with much less load, isn't it? It will run slower only if it really has almost nothing to do, or if it is overheated. The ARM will r...

Re: Custom RPI4 Bootloader

ah yeah, so a savy user could still "brick" such model4's in a server setup, but only using a properly signed recovery.bin, but its a bit different from keeping it working but detatched from the management framework I would have thought that if someone has physical access to your server, Pi or othe...

Re: ZFS for Raspbian

I've integrated a PR from procount which tweaks the build scripts to make changing to a newer kernel release/version a bit easier, and updated the readme to document this.

Re: Easily run 64-bit Debian Buster packages on a Raspbian system: new RPi4 / RPi3 image released (systemd-nspawn, LXDE)

Ah. Apologies - I suspect I have forgotten to switch to the 64-bit kernel. My mistake. That's really good news that it was just my mistake actually, as I was worried I would no longer be build ZFS modules for my main Pi 4B.

Sorry!

I was unable to get this working on the latest Raspbian version (2020-02-05) - the service failed to start. Also, are we to assume to that this functionality is about to be integrated into Raspbian?

Oh, BTW, that page says 4.19 EOL is December 2020. So, the Raspberry Pi will have to move on from 4.19.
Raspberry Pi will be moving to 5.4 after 4.19 - no idea about timescale though. My guess would be they will move to 5.4 this year at some point, but that is purely a guess.

This implies, by the way, that when Raspbian goes fully and exclusively 64-bit, the Pi0 dies. Only if you assume that when Raspbian goes 64-bit they stop developing the 32-bit version. Given the many previous public statements about not abandoning customers, I'm pretty sure Raspberry Pi will end up...
