Adding a modem increases the cost of what a customer sees as a black box, and asking then to plug a telephone in every major security breach is awkward, compared to going in via ssh and just fixing it. Nor is it always convenient to have two machines linked together by null-modem cables. So, how safe is it to make and build a new world and kernel, and just to kill off most processes instead of actually dropping down to proper single user mode? I've done that a few times, but are there any really good reasons why you shouldn't do this all the time? -- W. Palfreman.
