Recently, the patch required to boot the next with dhcp
was committed to the current netbsd cvs tree.  Unfortunately,
another change in that tree causes the NeXT to ignore the
boot file filename in the dhcpd.conf file and instead always
do a tftp request for a file named "boot".  This should probably
be looked into.

I recommend using bootpd instead of dhcpd to boot the next.
I continue to use dhcpd here only because my server needs to
serve dhcp requests to other hosts on the subnet.
