froller at metis:/etc/event.d$ less /etc/event.d/rcS

# rcS - runlevel compatibility
#
# This task runs the old sysv-rc startup scripts.

start on startup

stop on runlevel

# Note: there can be no previous runlevel here, if we have one it's bad
# information (we enter rc1 not rcS for maintenance).

...

also, please end post as it makes it easier to keep up with the
conversation.  Hope this helps.
