Ever heard of snapshots? Very cool stuff for restoring and backing up your data in an instant. Enter BTRFS (or ZFS): filesystem that lets you restore your / or /home (or any other folder when set up) before system boots to broken one, denying fear of broken updates, just dont forget to make some snapshots or use tools to make them for you from time to time. I use BTRFS since its already built in kernel and seems easier to set up.
