* Currently we support the following OSes:

* - Darwin (Extended Attributes)
+ * - FreeBSD (Extended Attributes)
+ * - IRIX (Extended Attributes)
* - Linux (Extended Attributes)
* - NetBSD (Extended Attributes)
- * - FreeBSD (Extended Attributes)
* - OpenBSD (Extended Attributes)
* (As it seems either they never implemented xattr or they are removed
* the support as it stated it was in version 3.1 but the current syscall
* might eventually support xattr on OpenBSD when they implemented them using
* the same interface as FreeBSD and NetBSD.
