NIS domains general question

Happy New Year managers.

I recently disassembled a NIS domain involving two Tru64 servers, and 
took the older one out of service.  Now I'd like to build a new NIS 
domain connecting the remaining Tru64 server (which was the Master in 
the old NIS domain) to a Linux box.  I'm not sure which to make the 
Master and which the Slave.  Does anybody have any 
recommendations?  I notice that Linux has no rcmgr and no 
/etc/rc.config.common which makes following some of the instructions 
in nis_manual_setup a little difficult.

All answers much appreciated
