True, single-user mode is not intended to be the normal way of booting
up a system. It's a bit like having to start up your heart, lungs, etc.
when you get up --- if you forget something, things would go wrong:).
Any security gained from single user mode can be achieved in multi-user
mode with proper configuration.
Still, stuff learnt for purely education reasons sometimes helps.
Any sufficiently advanced bug is indistinguishable from a feature.
