Description of problem:
At the end of /etc/init.d/halt, a UPS driver program may be called to turn off
the UPS. There are now new UPS driver programs that are USB based. In order for them to work, /proc/bus/usb/devices must be available read/write at that time.

I think there is no problem delaying the umount for /proc/bus/usb/devices and
the remounting of /proc until after the above code. Doing so unfortunately gets
relatively ugly. I will attach my hack, but please do it better!








Version-Release number of selected component (if applicable):
initscripts-7.93.7-1

How reproducible:
Always

Steps to Reproduce:
1.run on the UPS and wait for the low battery shutdown
2.read the error message if you can!
3.
