The init scripts support VLANs and bridges out of the box. Adding more scripts is not necessary.

I concur that separating the 4 interfaces as the original author suggested is a poor use of resources. If there are any policies in place for physical network isolation for management, it would be a better idea to get a LOM or a separate NIC for out of band management and bond the 4 primary interfaces for general traffic.
