What was the problem:
On reboot, c1sus was in a strange state. The epics IOC was running, along with tpman, but there were no loaded front ends.
People had to manually run sudo insmod c1SYSfe.ko.
What was the cause:
Awhile back Alex had commented out the line in the rc.local file which actually loaded the front end modules (i.e. c1x02fe.ko, c1susfe.ko, etc). This was while debugging. He never put it back.
What was the solution:
I uncommented the following line in /diskless/root/etc/rc.local file on the fb machine:
Now on reboot, the c1sus machine should start up all the front ends listed in the rtsystab file, located in /diskless/root/etc/ on the fb machine.
