Init script $named boot facility

The LSB specifies a handful of system based boot facilities.

http://www.linuxbase.org/spec/refspecs/LSB_1.3.0/gLSB/gLSB/facilname.html

Among them is "$named" which is described as: "daemons which may provide 
hostname resolution (if present) are running"

I am looking for some clarification on what that REALLY means.

It looks like the other items on the list all have to do with basic system 
resources in order for things to operate properly... Thinks like making sure the 
clock is right, mounting filesystem(s), etc.  This $named, does it mean that a 
domain name server such as "bind" has been started?  Or does it mean that the 
system is now capable of hostname resolution, i.e. /etc/resolv.conf or 
/etc/hosts is configured properly.  The second seems to be the intent as far as 
I can tell, but I'm not sure.

Any guidance would be appreciated on this.  (I am both interested from an 
applications point of view on when I should require this, and also on a 
distribution point of view on when I can safely "provide" this.)

Thanks,
Mark
