I did indeed RTM. Notice that the command I use to start the
transition is 'telinit 1'. After I do that, according to inittab,
init processes the commands in rc.K. At the end of that file is
the _same_ command I used to start the transition, signal delay
notwithstanding.

Do you see what I mean? I could just as easily issue the command
'telinit -t 1 1', and the commands would be identical. At what
point does init stop processing commands and give me a prompt?
