Actually, the way I'm thinking of it now would be to have a second system object
(sub-systems?), which would store your management info, and then link your main system to
that. This would be a 1 to 1 relationship, that way if you rebuilt a system onto a blade
(as noted below, this is a gotcha), you just reassign the sub-system object to something
else that needs management, put it in reserve, or just delete it.
Again, I don't know what we're going to do with the linkage constructs
here. If it's simply managing DHCP/DNS, I don't think we need it. If
we start to do more about OOB management, yes, but I'd subscribe to
YAGNI [1].
