Entering the issu commitversion command at this stage is equal to entering both the issu acceptversion
and the issu commitversion commands. Use the issu commitversion command if you do not intend to
run in the current state now and are satisfied with the new software version.
Note The rollback timer can be configured only in the ISSU Init state.
