Description of problem:
A set created in System Set Manager cannot be rebooted, each machine must be rebooted individually.


Version-Release number of selected component (if applicable):
RHEL5 machines

How reproducible:
Always with RHEL5 machines

Steps to Reproduce:
1. Create a set
2. Install provisioning modules on machine
3. Try to reboot set: https://rhn.redhat.com/network/systems/ssm/misc/reboot_systems.pxt
4. No machines available for reboot
  
Actual results:
The web site doesn't give you the option to reboot any machiens.

Expected results:
To be able to reboot all machines at once.

Additional info:
A workaround is available by individually rebooting each machine at https://rhn.redhat.com/rhn/systems/details/Overview.do however this is long and tedious and prone to error as the reboot time needs to be specified for each machine independently.
