Thanks, Pádraig.

I assume that bugzilla report is only related on a very abstract level:
The reporter of that ticket is suggesting special behavior after a 
getxattr(acl_stuff) call returned ENODATA, in which case following 
getxattr(acl_stuff) calls might of course have other results.

I'm referring to getxattr(acl_stuff) calls that return EOPNOTSUPP, 
because the file system does not support ACLs / extended attributes, in 
which case all following getxattr(acl_stuff) calls will definitely have 
the same result (plus the other lgetxattr(selinux_stuff) calls, which 
simply cannot provide any interesting information when selinux is 
completely disabled on a machine).

Best regards,
Sven
