Description Warren Togami 2019-08-02 05:05:38 UTC
Description of problem:
Since a recent version of Fedora appliance-creator or anything else that uses dnf within a chroot will fail with errors due to the host's selinux policy. "setenforce 0" allows it to work. Perhaps there is a less brute-force policy boolean than setting the entire host to permissive.

appliance-creator is probably better off testing if it would fail, and to bail out early with an informative error message.

This is one of several examples of common failures that can happen in a chroot.
