It never left draft status, yes. I don't understand all the relationships between posix.1e, all different ACL and extended attributes implementations, but the fact is that ACL's and extended attributes are supported nowadays filesystems. But we happen to have sys/extattr.h and friends no thirdparty software supports. A lot of such software breaks though if it relies only on existance of headers. -- Hasso Tepper
