Any thoughts? It means that you're trying to archive a file system which isn't actually a file system -- in this case, /proc. You can use gtar's -X option to exclude /proc and other non-file system paths from your archiving. You don't happen to be using procfs on a 5.x system, do you? procfs is notoriously insecure (and, in my opinion, its very functionality is insecure -- you shouldn't be able to see anything about anyone else's processes. Period.). If you are using it, why do you need it?
