[K12OSN] Doing the Pivot Root - befuddling

[Petre Scheie]

Thanks, Jim.  I added the lines to my dhcpd.conf file, thusly (line 
numbers added here for clarity):

1 host wendolene {
2        hardware ethernet     00:20:AF:14:DB:0B;
3        fixed-address         172.26.18.5;
4        filename              "/lts/vmlinuz.ltsp";
5        option option-128 code 128 = string;
6        option option-129 code 129 = text;
7        option option-128 e4:45:74:68:00:00;
8        option option-129 "NIC=3c509, 
MOPTS=nolock,ro,wsize=2048,rsize=2048";
9    }

But when I try to start dhcpd, it says "option definitions may not be 
scoped." in reference to lines 5 and 6.  I tried commenting them out, 
thinking they were perhaps just examples of the syntax, but then the 
client says it can't find the 3c509 module during the modprobe stage.  
Suggestions?
