Renaming a driver is a serious pain.  It's not just /etc/hostname.*
that's affected, it's /etc/dhcp.* and potentially many other files
such as /etc/ipf/ipf.conf and /etc/ipf/ipnat.conf, /etc/gateways,
/etc/sfw/smb.conf, /etc/inet/dhcpsvc.conf, /etc/inet/ndpd.conf,
/etc/quagga/*.conf, /etc/zones/*.xml, and probably dozens of others
that I'm too lazy to locate at the moment.

Basically, as we said with the ipge transition before (2004/782), you
can't do it in any non-trivial configuration.
