I thought anything other than a 'shutdown' was liable to damage the filesystem ? Is c-a-d setup in someway to be a synonm for a quiet shutdown [doesn't seem very likely] (I appreciate I don't have a lot of choice :-( No, Ctrl-Alt-Del will bring down the system smoothly. It will sync disks. But off-hand, I can't remember if it is equivalent to shutdown(8) or reboot(8). > This seems like an area of ambiguity to me. Plenty of people seem to run *nix boxes without UPS's which would seem to indicate that just taking the power off the box can't be _so_ disasterous. Comments ? Experiences ? Filesystems are not as delicate as they were long ago (long being more than five or ten years). Generally, pulling the plug or power cycling a system may mess up a few files, but it generally won't screw up your filesystem beyond hope. As for all the UNIX boxes out there without UPSes, look at all of the NT boxes. They just as bad off when the system goes down hard if they are living on NTFS. Hard-stopping a modern filesystem is a Bad Thing, but it is not /usually/ a disasterous thing. -- Crist J.
