Description Bill Nottingham 2006-12-15 16:28:55 UTC 
+++ This bug was initially created as a clone of Bug #219758 +++

Description of problem:
At two places, the init.d halt script has a 2 second sleep after unmounting
certain paths and before checking whether the action was successful. Under
typical conditions, the 2 second sleep is completely unnecessary. Collectively
these two sleeps slow down the shutdown process by almost 4 seconds.

Version-Release number of selected component (if applicable):
N/A

How reproducible:

Steps to Reproduce:
1. Execute /sbin/halt and measure time. 
2. Apply attached patch, run /sbin/halt again and measure time. 
3. Shutdown will be 3-4 seconds faster with patch.
  
Actual results:
See above

Expected results:
See above

Additional info:
On most systems even the 0.1 sec sleep I included is unnecessary, so feel free
to remove it.

The patch also comments out the "devremaining" variable assignments that look
like they have been left behind accidentally.
