Bug 2418072

Description of problem:
Additional info can be found here: https://discussion.fedoraproject.org/t/selinux-is-preventing-bwrap-from-mounton-access-on-the-directory-tmp/175344
SELinux is preventing bwrap from 'mounton' accesses on the directory /tmp.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that bwrap should be allowed mounton access on the tmp directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'bwrap' --raw | audit2allow -M my-bwrap
# semodule -X 300 -i my-bwrap.pp
