Oh, there's Android users for this? The users I was aware of were non-Android. Though even so I'd have thought that given that SELinux is a superset of Unix file permissions it ought to be sufficient to be able to use them. I'd been thinking people were suggesting SELinux as a replacement for file permissions, using the single file and the greater capabilities of SELinux.
