If Linux would like to bulletproof then they would implement ZFS Boot Environments that FreeBSD has with beadm(8) or bectl(8) tools.

With ZFS Boot Environments you can change any aspect of the system/upgrade everything/change packages and even leave system in totally broken state ... and just reboot to one of other Boot Environments that you created earlier - once you 'got it' how awesome and useful that is - you will want that everywhere.
