This one seems useful on Solaris. Assuming the name is reflective of its purpose it says to me that files with this attribute should not be included in backups. For example tar/cpio/pax might pay attention to that attribute but 'zfs send' would not. > The following files will be added to the top level directory in the > extended attribute namespace of all regular files: > > -r--r--r-- 1 root root 88 May 16 16:17 SUNWattr_ro > -rw-r--r-- 1 root root 484 May 16 16:17 SUNWattr_rw Why SUNW Rather than org.opensolaris as the prefix ? The latter would IMO be more appropriate today given these are OpenSolaris specific rather than "Sun Microsystems Inc" specific. -- Darren J Moffat
