No, it will not move any devices that already exist. It will either
insert into the chain in the first hole it finds, or append to the end of
the chain. This way, if you have drives sda through sdd and you remove
sdb, then when you do an add, the new drive will take the now vacant sdb
slot. For the common case of wanting to replace a failed drive, this is
the perfect behaviour.
