Our specific-to-ISU version of netreg uses omapi
to do host adding. There are some tricky bits
1) we had to modify dhcpd to NOT add the entry
to the leases file (since we are adding it
to the config file and duplicates are bad).
2) We use class/subclasses to separate clients
to verious service categories (different
subnets on the "same wire"). We have been
thus far unable to make omapi for for adding
subclasses :( :( :(
