If you've not had to do it for 15 years, entombing probably isn't for you. When was the last time you took care of 500+ users on a single machine. Users delete files. Users clobber files. Users intentionally make changes to files and then don't want them tomorrow. We have _serious_ users around here with serious needs. We have all of our important data on hardware RAID 5, and we still do nightly backups to DLT. DLT's are fast, but pulling one file off tape (which would happen) can take 45 minutes to an hour, even with good tools like Amanda. I don't really need entombing at home, but I sure take advange of it when I shoot myself in the foot. I guess that real UNIX studs don't ever do that, or apparently don't live to tell the story. The best part is if you don't like it, don't use it. ENTOMB=no, and you're completely screwed as usual when you delete a file. ;-) - Steve -- C.
