I don't think there's anything different in the *kernel* when switching single user. However, key programs such as init, are *not* running as single user mode. And, indeed all daemons and gettys are shut down, so the only process running should be your sh'ell, given that you have not started the make world process. The thing with multi-user, is that it's made to keep a lot of stuff running. Just having getty running on a port might be a problem on a major system upgrade, if this port is connected to a modem where a user connects and starts a shell etc... The other thing is that to "shutdown lotsa daemon" is often equivalent to "shutdown now" (switch to single user)....
