The buggy behaviour won't affect the host system, but the jail could

for all folks who have deep consideration of FS:
We do not know well around MAC and ACL. Someone knows
well around those, please teach us. Does MAC have
a information of schg of chflags?
for all folks who have deep consideration of FS: part2
Yeah, it is possible to make capability for setting the
ALC and MAC information to the upper layer of the unionfs.
With that, we must consider the policy that what
information should be copied to shadow file when it makes
shadow file. Without the policy, we cannot make it.
We want to know your opinions if you have deep
consideration of it. What do you make of it?
