> WHITEOUTS??? What is this? IIRC, whiteouts are (would be?) used for the union filesystem (similar to Sun's "translucent" filesystem). The union filesystem allows one filesystem to be mounted "over" another, where you see files in both filesystems with those in the "upper" filesystem overriding those in the (typically read-only) "lower". A whiteout in the upper filesystem hides one in the lower, allowing you to delete files from the union. Undeleting such a whited-out file would just be a question of removing the whiteout to expose the original again. -- Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
