Description of problem:
Plugged in USB stick
SELinux is preventing boltd from 'read' accesses on the lnk_file driver.

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

If you believe that boltd should be allowed read access on the driver 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 'boltd' --raw | audit2allow -M my-boltd
# semodule -X 300 -i my-boltd.pp

Sorry, I was too quick here, I think the change in bug 1754360 (selinux-policy build 3.14.4-36.fc31) might actually *cause* this.

rpm -qa "selinux-policy*"

As a result of this boltd does not work at all anymore:

NB:it can not find any thunderbolt hardware (should appear between "udev: enumerating devices" and "dbus: exported domain at").
