Disable automatic updates. Add a bunch of third-party software. Install at least one bit of hardware so nonstandard you're forced to install a driver from source. Then do all the system updates, and immediately reboot. Ideally, nothing should break, because all the upgrades will have proceeded cleanly and migrated everything forward nicely. Doesn't always happen. The more third-party software and nonstandard hardware you throw into the mix, the more likely you will run across one of these corner cases.
