Hi all,

it seems that we've missed a new runtime dependency being backported
recently into Icehouse. The patch is [1], and it introduced
conntrack-tools dependency for L3 agent. This turned out as a problem
for existing distributions, specifically RHOSP5 [2] which is built for
both RHEL6 and RHEL7. In case of RHEL7, conntrack-tools is not
available neither in base OS repos nor in RHOSP5 specific ones. So Red
Hat will need to import the package into RHOSP5 repos. That's not
convenient but doable. The problem starts when you consider importing
the package for RHEL6 too. It may turn out that some support from
kernel may be missing (we're going to check that in the very near future).

If RHEL6 conntrack-tools won't play nice, we'll be forced to patch the
fix out for the platform. I wonder whether we'll consider reverting
the patch in upstream if that's the case?

So my general point is that we should pay more attention to those kind
of runtime dependencies sneaking into stable branches, because it may
result in huge problems in downstream.

Also, consider this email as a heads-up for other distributions.
Should we update release notes for the latest release to include that
info?
