No, init does NOT create the /dev/initctl fifo. It just assumes it's there.
Therefor the correct solution is to create it in some startup script and do
a kill -USR1 1 to tell init to open it.

Oh, and please do not create it in devfs itself - I hope to convince
some people to have open() on a AF_UNIX socket to behave as connect(), and
then move to using a Unix domain socket instead (so I can use SO_GETCREDS
and do all kinds of neat stuff in init for a normal user - for example
getting rid of the suid bit on xterm..).

Mike.
