Description of problem:
Kudzu does not do a twiddleHotplug(1) if
/etc/sysconfig/network-scripts is not found, leaving
/proc/sys/kernel/hotplug set to /bin/true on distributions that do not
have /etc/sysconfig/network-scripts.

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


How reproducible:
Always

Steps to Reproduce:
1. cat /proc/sys/kernel/hotplug 
2. kudzu -c NETWORK -p -t 40
3. cat /proc/sys/kernel/hotplug 

Actual Results:
# cat /proc/sys/kernel/hotplug 
/sbin/hotplug
# kudzu -c NETWORK -p -t 40
# cat /proc/sys/kernel/hotplug 
/bin/true


Expected Results:
