Sure, I previously did that umount check on physical patitions, but my current problem was, that the filesystem is a tmpfs. As soon as I do the umount to check if it is no longer used, the contents of the filesystem is lost and can't be processed/stored away for later use. On the other hand the final processing can't start as long as there are active processes accessing the filesystem. I did not consider that mount bind feature to hold a copy of the filesystem during umount of the original mount point. So Lauren's solution fit's perfect. -- Harald _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
