I understand the confusion, because the discussion looks like it's about kernel versions. But if you click in, what's being tried monitored & reverted is boot loader entries. From the second sentence in https://systemd.io/AUTOMATIC_BOOT_ASSESSMENT/ https://systemd.io/AUTOMATIC_BOOT_ASSESSMENT/ : > The Boot Loader Specification describes how to annotate boot loader entries with a counter that specifies how many attempts should be made to boot it. Which include kernel parameters. Which include the root. As a btrfs user, my system could take a snapshot before applying an update, & set that as the fall through loader entry, so that if boot fails I go back to that previous state. I'm again finding myself 100% on Team Lennart here. Again this seems like the obvious right & true path, & like we obviously should be doing this.
