Description Dominik 'Rathann' Mierzejewski 2018-01-03 11:11:01 UTC 
Description of problem:
Ran a build using mock -r fedora-rawhide-i686 on my x86_64 F27 machine, then aborted it using Ctrl+C.
SELinux is preventing systemd-machine from 'read' accesses on the lnk_file os-release.

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

If you believe that systemd-machine should be allowed read access on the os-release lnk_file 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 'systemd-machine' --raw | audit2allow -M my-systemdmachine
# semodule -X 300 -i my-systemdmachine.pp

Comment 1 Dominik 'Rathann' Mierzejewski 2018-01-03 12:25:27 UTC 
It looks like it's 100% reproducible, i.e. happens every time I Ctrl+C a running build.
