    Sure, our testing coverage here is far from perfect, that's never
    been in
    dispute. It's always been best effort (which there has been limited
    in this
    space) like I'm not aware of anything doing any upgrade testing with
    virtuozzo enabled, or any of the other random ephemeral storage
    backends,
    **cough** ceph **cough**.  But, as I said before just because we
    don't catch all
    the issues isn't a reason to throw everything out the window.


So now we have identified some other examples recently added to the
codebase, that where not noticed by grenade for one reason or another.

Do we:
A) revert+postpone the virtuozzo changes until the next release?
B) add a releasenote saying you need to update the rootwrap filter first?

I already anticipated this when reviewing the changes that added the new rootwrap filters and made sure there was a note about this in the release notes.


(Yes, this is a test)

It's boring, but not that hard to manually diff filters between releases
- I can do an audit if we'd like to build a list of other such changes.
