Yes. If a Smack aware application reads /proc/self/attr/current
it has no way to know if what it sees is a Smack label or an
SELinux context. True, the application can look elsewhere
(i.e. /sys/kernel/security/lsm) to find out which is enabled.
But the real fix is for Smack to use a different interface
than SELinux. Which is what this does. True, it will be even
more important when/if major stacking comes in, but it is still
significant now, and I would like to have it regardless of
the future acceptance of major stacking.
