PS1 prompt based on who logged in

Question

I've got a nice PS1 prompt that I want to only be used when user 'gatty' uses su for root.

PS1='\[\e[32m\]#\[\e[37m\] '

When other users like 'george' etc login, I want them to get the standard PS1 instead of 'gattys'.

Is this possible, how would I go about doing this?

Thanks!

In root's .bashrc, check the contents of /proc/self/loginuid, and set your custom PS1 variable only if it equals your UID.
