The problem is that SELinux doesn't know anything about the new filesystem 
type, and specifically, to treat it like procfs.  There are a couple 
workarounds we can try to prevent this specific problem from cropping up 
again.

I wouldn't say it was a bug, more a consequence of necessarily imperfect 
encapsulation of the security code via LSM.  It's just something we have to 
keep an eye out for.
