Ok, so ipvsman is always looking at the ipvs kernel table for it's 
information and does not interact directly with any daemon.

Ok, so ipvsman cannot create a config file.  But if you use ipvsman to 
adjust the function of the realservers then how can you preserve those 
changes over a reboot?  Who/what takes care of changing the config file 
to reflect the realtime changes you made with ipvsman?  Must this be 
done manually as in duplicating your changes, this time to the config file?

Yes, I think I will try this.  I should have time in about 2-3 days to 
start.

That sounds good.
