Petraeus will have to notify his probation officer if Trump taps him as secretary of state
"The defendant shall not leave the Western District of North Carolina without the permission of the Court or probation officer. Travel allowed for work as approved by US probation office."
A Secretary of State must travel the world, but Petraeus can't leave his corner of North Carolina without the permission of a low-level civil servant! That probation officer could really have some fun with this!
