I think that you might be missing the reason of existence of take over.
It suppose to "take over" the kernel team instance in case for example
the teamd segfaults or something. The intension was to run new teamd
instance taking over the kernel instance with exact same config.
Why are you doing this?
Want to change the teamd config without losing the interface config
(addresses, vlans etc) - want to avoid deleting the team device when
updating team config.
Cheers.
