  • Just watched some videos on btrfs. I start to understand the conceps. Perhaps I should also look into how exactly

    On windows and the “recovery partion”. I guess what you say is that it should always be possiblity to boot in some kind of system, but it will not happen automatically as there is no way for a system to detect that the system completely hangs.

    Thinking about it. It kind of strange. Embedded systems have watchdog interrupts that get fired if the system hangs (i.e. if it does not provide a “yes, I still live” signal every “x” milliseconds). Does a PC not have something similar?





  • Concerning linux, yesterday I was watching this video on computerphile on the crowdstrike incident. https://www.youtube.com/watch?v=rlaNMJeA1EA (*)

    What is interesting is the comment made in the video on how chromebooks do software upgrades with dual “OS” disk-partitions and the ability to rollback to the previous OS-partition.

    Question: is something like this also possible on one of the major linux distros? (debian, ubuntu, rocky, …) What would be the procedure to do this kind of “dual partition” system-upgrade?

    (*) a great video that explained some of the technical details in a very clear way, including some very interesting ‘lessons learned’ and "what if"s If you ever need to explain crowdstrike to your manager, this video is a good start.
