option 60

[David Yeske]

I have been using a patch that is similar to this for a while with grub.  I 
think it would be
useful for grub to send an option 60 tag.  This may not be the best way to do 
it, but it works.  I
was unable to get the version number into the option 60 tag by using VERSION or 
version_string. 
Maybe sending the version number is not really needed though.

So with this in my dhcpd.conf I have more control over the menus...

if substring (option vendor-class-identifier, 0, 4) = "GRUB" {
        option option-150 "/boot/grub/hostname.lst";
}
