Hi Glenn.
Thanks for your feedback.
This code is intended to run only on AI clients, and a VirtualBox client
won't show vboxnet0. (I just verified.)
Thanks,
Jack

Hi Dave and Ethan.
I wanted to run by you the algorithm for getting the proper IP
addresses for the Derived Manifests project, to make sure I've got
my bases covered.
For the benefit of others: the IP addresses will be part of the
environment set up by the Derived Manifests Module (DMM). The DMM
will then run a script which can call a utility (aimanifest) to make
system-specific customizations to a manifest before AI installs from
it.
The design spec allows for only one IP address to be propagated in
the environment: SI_HOSTADDR. However, there could be a system with
multiple host adapters connected, and so there can be multiple
addresses. My algorithm addresses this and introduces numbered host
addresses and an environment variable that returns the number of
host addresses.
It isn't clear to me, but does your algorithm take into account
interfaces like the one virtualbox sets up for instance?

vboxnet0 is certainly not an interface that you'd want to use even
though it's configured like any other interface.
