- I do not see any reason why a node could not boot off a disked node on its
- own (i.e. the diskless node's) primary network; it seems irrelevant whether
- that network is primary or secondary for the disked node. We have a Domain
- internet composed of 5 TR rings and one ethernet (plus the 'outside'
- ethernet, but that does not carry Domain traffic). We occasionally boot
- nodes off the gateway nodes, from the primary or the secondary side. In fact
- we do have such an arrangement permanently: my own node is a disked 425t.
- Its primary network is TR; there is a diskless 425t on the ring booted off
- it. It also provides 'rtsvc -route' services between the TR and the
- ethernet, and there is a diskless 425e on the ethernet booted off it.
-
- Hope this helps.
