No, you mis-understood my idea. It is not to secure root password, only to log the reason before shutdown/reboot (like Windows 2003 severs)
my idea is: "Admin users can shutdown/reboot, but everytime they want to reboot they have to answer some questions to keep record of servers shutdown/reboot".

Question could be like this:
1/ what is your name ?
2/ Reason of shutdown/reboot ?

And they may answer:
1/ John Mayer
2/ new package installed

After they answer those questions, the real shutdown/reboot process will start.

And we have log file record that:
[Date and time] [name] [action] [reason] [login from]
