This all reminds me of a problem in vxworks (based on an old bsd
stack) where an NFS mount would 'lock' a routing table entry for
a specific host, causing grief when the interface was deleted
and an entirely different network created (different default
route and nameserver as well as everything else).
Whether the current netbsd stack has the same feature is
open to experiments.....
