	A kernel configured with NFS_BOOT_BOOTP is unable to mount its
	root file system from the network.  I consistently get:

	nfs_boot: getfh - no pathname

	tcpdump shows that the response from dhcpd to the BOOTP request
	does not, in fact, contain the root path name; thus I suspect
	this may actually be a bug in dhcpd (same vintage as kernel).

	A kernel configured with NFS_BOOT_DHCP boots correctly.

	The relevant stanza from dhcpd.conf is:

        host {
                hardware ethernet 00:10:4b:62:ae:3c;
                option root-path "/u2/export/root/quiche-lorraine";

	And the aforementioned tcpdump output is:

	06:09:31.694376 0:10:4b:62:ae:3c ff:ff:ff:ff:ff:ff 0800 534: >  [udp sum ok] xid:0x7ffffff vend-rfc1048 [ttl 1] (id 6)

	06:09:31.718850 0:10:4b:62:ae:3c ff:ff:ff:ff:ff:ff 0806 60: arp who-has tell

	Try to boot using NFS_BOOT_BOOTP.

	Not known.
