@bse @pid_eins @vurpo If you deliberately bypass the system integrity and safety features, then they won't save you. It doesn't matter what those features are. If you blindly sign initrds, checking won't help you. If you blindly mark a boot config as good, or if you replace your rollback image, or whatever... The system won't save you from yourself infallibly. You'll still want staging, and monitoring, and disaster recovery.  @pid_eins @vurpo Since both entries would be using the same kernel and hence use the same /lib/modules/$(uname -r)/, you need a mechanism to have multiple versions of your modules folder. If you're serious about preventing older boot entries from breaking retroactively, i think full system snapshots are the only option. Short of that, there might be some compromises like bundling a kernel and all modules, which of course does not protect userspace, but might be easier for commonly used distros. |
@bse @pid_eins @vurpo openSUSE with snapper can reboot into a full older snapshot of the system (except user data), which has saved my butt a few times.
