Is anyone actively working on this? Having been 'caught out' on this subject more than a few times, usually by shutting down a remotely located box that was mounted via smb or cifs, and found the only way to get sanity back to the rest of the system was a hard reset of every other box that was also sharing that mount, I would think this is a worthwhile project. Take that as a yes vote, from somebody who isn't franchised to vote on it in the first place, I'm just a user, usually playing the part of the canary in the coal mine. >Mike -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
