Description robert 1999-11-08 20:18:36 UTC

If somebody does command:
touch /tmp/confirm
RedHat 6.1, when rebooted, automatically enters in interactive startup
So no process from /etc/rc?.d/S* will be started
and system won't boot up until admin comes and presses N or Y or C on the console
Solution:
in /etc/rc.d/rc.sysinit it should be removed before /sbin/getkey will be spawned
I think a few last lines from /etc/rc.d/rc.sysinit should be like these:
CONFIRM="no"
if [ "$PROMPT" != "no" ]; then
   /sbin/getkey i && CONFIRM="yes"
fi
[ "$CONFIRM" = "yes" ] && touch /tmp/confirm || rm -f /tmp/confirm || true
wait
Better solution: MOVE this flag file to NONWORDWRITEABLE directory, like /var/lock,

PS. There's another problem with /tmp/confirm: if admin wants system
to enter interacive startup by pressing key 'I' and /tmp/confirm exists and it's a directory.

moved to /var/run/confirm in initscripts-4.63-1.
There's no need to do the prior removal, as /var/run is
cleaned at each boot.
