That would be a bug.  What kernel are you using and what type of
filesystem do you have on /efs?  The filesystem code has to make a call
to SELinux on inode creation to get the security attribute name and
value, and then set that attribute as part of the inode creation
transaction.  The native Linux filesystem types include that support
already.  We had to patch yaffs2 to do it.
