Description of problem:
In fc17:
[root@ibm-x3550m3-01 ~]# kdumpctl restart
Stopping kdump:
Detected /etc/kdump.conf or /boot/vmlinuz-3.3.2-8.fc17.x86_64 change

Back in rhel6/5, we can get:
[root@localhost ~]# /etc/init.d/kdump restart
Stopping kdump:                                            [  OK  ]
Detected change(s) the following file(s):
  
  /etc/kdump.conf
Rebuilding /boot/initrd-2.6.18-308.el5kdump.img
Starting kdump:                                            [  OK  ]

The status of the specific kdumpctl start/stop is missing, we can't really tell whether the kdumpctl start/stop works or not from the output. But sure we can use `echo $?` everytime we use kdumpctl.
