Try adding what to /etc/netsvc.conf? What is the syntax?

I know how to add syntax for /etc/hosts (i.e. do I search DNS or /etc/hosts first, etc.). I know it can also be used to determine the order to search e-mail aliases. That's only two of the 15 things nsswitch.conf does. I haven't seen any syntax to tell it an order to search for home directories to NFS automount. If it can be done, by all means, tell me how.

Thanks!
