Apps can cause selinux denials by accessing CE storage and/or external storage. In either case, the selinux denial is not the cause of the failure, but just a symptom that storage isn't ready. Many apps handle the failure appropriately. These denials are not helpful, are not the cause of a problem, spam the logs, and cause presubmit flakes. Suppress them.
