full root shell necessarry?

[budman7]

I use su to get into root so I can install modules.
But I keep getting this error

"You are not running a fully initialized root shell....."
Then it proceeds to compile the module.
Just curious, why do I need a full root shell, and if I don't use it, will it break anything?

Just using su instead of su - is pure habit.

when you run 'su' instead of 'su -' there are a certain number of environment variables from the original user environment retained. This may be a security concern. Best not to use 'su' without '-'. While lunar works okay it is still recommended to NOT use 'su' but always 'su -'

Thank you for clearing that up.
I will just have to break old habits.
