I am not sure I got your point.
I think unplugging and plugging network cable in should not cause any change
whether dhclient runs or interface is statically configured, nor should it
depend on whether interface is configured from boot script or manually.
As an alternative, from user's perspective equal, would be kill dhclient on
unplugging and starting it again on plugging cable, but this looks to me as
unnecessary complication.
I did not test this behaviour on my -current yet, though. Maybe I do not know
all events coming into play here, either.
