Description of problem:
We have implemented our own fence method which was working fine until the U3 
upgrade.  We have a perl script in /sbin which is called by the fence daemon.  
The perl script uses a system command to call a bash script.  Both the perl 
script and the bash script work fine if called from a command line.  If the 
perl script is called from the fence daemon, the bash script either hangs on a 
read command or exhibits other strange behavior such as logger will not print 
a message to the system log.

Version-Release number of selected component (if applicable):
fence-1.32.18-0

How reproducible:
Every time.

Steps to Reproduce:
1. Invoke perl script from fence daemon
2. Invoke bash script using system command in perl script
3. Have bash script issue logger "message" 
  
Actual results:
No logger message appears in system log

Expected results:
Logger message in system log
