Description Adam Williamson 2019-05-30 18:22:39 UTC
Fedora-Rawhide-20190529.n.0 in openQA testing shows some new SELinux denials after a fresh install and boot. These did not appear in Fedora-Rawhide-20190527.n.0. These are the denials (I booted in permissive mode to check we got *all* the denials):

The obvious difference between the two composes is the arrival of selinux-policy-3.14.4-19.fc31, the previous compose had 18.fc31.

I'm not sure what practical effect this has, it doesn't seem to stop the network working at least.
