[openstack-dev] [fuel] FF Exception request for Fernet tokens support

Thanks guys. Feature Freeze exception request is declined then. Let's
polish this work before the next release, merge changes to upstream
puppet-openstack, and then just use librarian in the next release.
I'd like to comment Bogdan's email -
unless we fully switch to librarian, I don't agree with:

We can do whatever we need to do based on immediate needs for Fuel, but
with the converging plan. We can't break something in Fuel, for example,
just because we need to fix it puppet upstream first.
On a separate note, any idea why this email appeared in a new thread in my
inbox, not in the original one? My suspect is that Bogdan's client does
something weird with email headers...
