I and another engineer here are  in  need  of  some  net  wisdom.
Here's the problem:

on system V 3.2 performing an init S puts the system into  single
user  mode.   It also makes the terminal that executed the init S
the system console.  Also according to the man page init(1M), all
mounted  file systems are left mounted and only processes spawned
by init are killed. What the man page and documentation does  not
say  is  that  any  processes  i.e. daemons that were created via
script files in /etc/rc* are still running.  Which means that  if
you  perform  an  init  2  from this state then there will be two
copies of every daemon running.  Obviously this is not a  desire-
able state! :-)

The easy thing to do is just perform an init 6 which will  reboot
the  system.   In  the interests of getting the system back up to
multi-user mode in the shortest time, the ideal would be the init
2.    What can we do to go back to run state 2 without rebooting?
And is this a bug or a feature?

Thanks in advance for the help. Marc
