Hi,
As you know bootpc only grabs information and works well if the
interface is up and added on the routing table as a default. On the
other hand, ifup just executes bootpc without calling ifconfig and route
to get the interface up. If the pre-up command is used to bring it up
before running bootpc, it will fetch parameters from one's network and
do nothing else. Most people would like to use the bootp method in
interfaces and not to use bootpc to fetch and show parameters.
So please rename /sbin/bootpc to /sbin/bootpc-bin and save the attached
script as /sbin/bootpc instead.
Thanks, Kohei
