[plug] Interesting command that may make root access more fun ..

[Lyndon Maydwell]

Well I guess what I'm saying is that from a security standpoint, if a
user has the ability to use 'sudo su' then you must assume that they
have full access to your system. It will be too late to retract
privileges from them later. Giving them root access will ensure that
you're not harboring a false sense of security.

I do advocate the use of sudo, just not indiscriminate use.
