bug report:
	in lib/libstand/bootp.c:

	if (IN_CLASSA(myip.s_addr))
		nmask = htonl(IN_CLASSA_NET);
	else if (IN_CLASSB(myip.s_addr))
		nmask = htonl(IN_CLASSB_NET);
	else
		nmask = htonl(IN_CLASSC_NET);
should be:

	if (IN_CLASSA(ntohl(myip.s_addr)))
		nmask = htonl(IN_CLASSA_NET);
	else if (IN_CLASSB(ntohl(myip.s_addr)))
		nmask = htonl(IN_CLASSB_NET);
	else
		nmask = htonl(IN_CLASSC_NET);

which explains why gateway was zero, even if it was provided by dhcp.
it also explains why it hung trying to mount via nfs.
