What determines object name for dual interface machine?

["Brook, Bryan S" <bryan.s.brook@LMCO.COM>]

Hi everyone.

We are defining a collection and attempt to define it by an "object list".
Within this list we type in the hostnames of the machines to be included in
the collection. Sometimes the hostname we add isnt there.  Why?

Our machines have 2 interfaces:
DNS resolved names:  foo (FDDI) and foo_e (ethernet)

If I add foo to my object list -- It fails.
If I add foo_e to my object list -- It works.

Is this because foo_e was the first interface discovered for that machine?
If the topology database was dumped and rediscovered, the object name would
be whatever interface it found first?
How could we ensure the object names coincide with the "real" hostname?  Add
entries for FDDI interface in the seedfile?
