I don't think we support the DHCP swap options.  It looks like what you
want to do is use the swapfile option in rc.conf to add a swapfile on a
drive you are NFS mounting RW.

I'm not seeing any of the dhcp.* names space on my diskless machines.
The hostname gets set if options BOOTP is in the kernel but that's done
directly in code in sys/nfsclient/.
