Rather than consider 'which is better' I believe DHCP and DNS are 
pretty equivalent for this function.  Why not facilitate this
equivalence and provide for making responses from DHCP consistent
with those from DNS?

It would be nice if dhcp option numbers assigned could be paired
with well known names to be used in DNS SRV records.  This would
facilitate DNS and DHCP giving out the same information.  This will
be particularly useful if stateless DHCPv6 and multicast DNS become
pervasive.  A stateless DHCP and multicast DNS server might use the 
same database to answer a request for a particular service type.
