It would be difficult at best, unless you are only using it for a minimalist root and everything else is on some other filesystem type. Without xattrs, you do not have per-file security labels and therefore cannot set up automatic domain transitions on any of the executables in that filesystem or otherwise distinguish any of those files in the policy. Lack of xattr support in a native Linux filesystem is a significant drawback these days; xattrs are used not only for SELinux but also for ACLs, file capabilities, and various application purposes (user. namespace). reiser4 isn't in mainline AFAIK.
