Log:
test if plymouthd can access /dev/kmsg
Recent testing revealed that SELinux prevents the plymouthd processes
from accessing the /dev/kmsg device. The TC reproduces the situation.
In order to support the expected plymouthd functionality, I believe
that SELinux policy should allow the access. The TC looks for
appropriate policy rules and file context patterns.
The TC covers BZ#2256442.
