Describe what you need us to do:
As I'm inheriting maintenance of FMN, I will need to be able to sudo to root on the FMN hosts. Please add me to the appropriate FAS group.

When do you need this?
When you can.

When is this no longer needed or useful?
When FMN is dead and buried, and unfortunately that may be a long time.

If we cannot complete your request, what is the impact?
I won't be able to test the changes I'll make to FMN on staging, or investigate issues on prod.
