Whether or not MLS is enabled is defined by your policy build options.
In refpolicy, this is determined by the TYPE= setting in build.conf.
The upstream refpolicy defaults to "standard", which leaves MLS
disabled.  Fedora and RHEL use "mcs", which enables the MLS engine and
field but only uses categories with a different set of constraints than
"mls".  Fedora and RHEL also run mcstransd, a daemon for label
translation, which by default strips the ":s0" suffixes so that users
don't see them.

Disabling MCS/MLS in Fedora or RHEL may cause compatibility problems.
Such compatibility issues should be reported as bugs, since application
code should remain independent of policy, but such bugs have been
encountered in the past, and most users of Fedora and RHEL only use the
default policy that enables MCS.
