+`crash-before-switch-root`
+==========================
+
+What does this test?
+--------------------
+
+A simple known method to crash the system at boot.
+
+This can be used to check changes to the errors handling.
+
+
+Why is this scary?
+------------------
+
+Not scary at all. Only pretty useless in daily use!
+
+
+How is success defined?
+-----------------------
+
+The boot process should proceed normally (splash, etc), but be
+interrupted before switch root.
+
+The crashing happens *after* mounting /mnt, but *before* switching root.
+
+
+Running
+-------
+
+Assuming you are `cd`'d into the root of a Mobile NixOS checkout:
+
+```
+nix-build ./examples/testing/crash-before-switch-root && ./result
+```
+
+This will build for qemu-x86_64 by default.
+
+As always, be mindful of your `NIX_PATH`.
