Comment 8 for bug 1789551

I have made a Bionic version with the fix available for testing in [1].
I'd ask people to test this. Since it changes behavior of a default disabled feature this call applies almost exclusively to people that have set up qemu with "-sandbox=..." or configured libvirt to do so with seccomp_sandbox = 1 in /etc/libvirt/qemu.conf.

@Seth - might I ask you to do a nicely worked call for testing since you so nicely coined it "cajole people to test and report results"?

Depending on the feedback to that we can make a Bionic decision then.

Note: there are plenty of qemu SRUs in flight (one in -proposed, one waiting) this PPA is ahead to all of them to be useful for a while - none of the other changes affect seccomp execution in any way.
