bug#16094: bug: cp/mv cannot copy/move a file's extended attrs if they start with 'security'

[Linda Walsh]

I saved a file to my home directory on linux via windows.
I wanted to move it to /tmp.

I got:
 mv  /home/law/tmp/oVars.pm /tmp
mv: setting attribute ‘security.NTACL’ for ‘security.NTACL’: Operation 
not permitted

So what's up with this?  Shouldn't the NTACL be able to be stored/moved 
with the
file?
