Would it be worthwhile to have a field for which security features are
enabled for a file? Maybe with bits for if the file has ACLs (and which
type if the richacl code goes in) or for the selinux labels or other
similar types of data? The current version of ls I have does a huge
pile of getxattr calls along with all the lstat64 calls.
