System: NetBSD black 1.3F NetBSD 1.3F (XEMPLAR_CATS) #4: Mon Jun 15 17:57:31 BST 1998 root@fan82:/usr/tmp/netbsd-13f/src/sys/arch/arm32/compile/XEMPLAR_CATS arm32


>Description:
If dhcpd is set up to use dynamic-bootp, you can't specify a
filename for the bootp clients to use as you can't use dynamic-bootp in
a group section. Therefore, the only play to specify a filename is as
a global parameter, however this is ignored. The patch allows a global
filename to be specified which is only used as a last resort.
>How-To-Repeat:
The following /etc/dhcpd.conf will fail to boot a bootp client requiring
a valid filename:

option domain-name-servers 194.205.192.15;
max-lease-time 172800;
filename "/usr/export/home/ncd/boot";
get-lease-hostnames on;

shared-network XEMPLARNC {
  subnet 194.205.192.0 netmask 255.255.255.0 {
    option routers 194.205.192.15;
    range dynamic-bootp 194.205.192.46 194.205.192.46;
  }
}
