Thanks for the help Brent. I cannot get this thing right. I need to try more options.

You can always try your upstart job the way you had it, but I vaguely remember testing a similar upstart config a couple years ago and it not working as I thought it would. The strange thing that will occur when you have a failed filesystem check is your output just goes away on your 3270 as it gets directed to the iucv console. I don't like this solution, but I put in an echo statement that is directed to /dev/ttyS0 in /etc/rc.d/rc.sysinit so we could see the failure in 3270 and know to switch over to IUCV.
