Lessons Learned

This week I was bitten by a mistake someone made who hadn't learned the same lessons I had years earlier.

Put your lock files in /tmp. It's one of those things you learn the hard way. Since /tmp get flushed clean on every bootup of a unix system, this means that after a power failure or other hard reset, your systems will begin functioning normally. Otherwise, you can count on no one noticing your otherwise smoothly running tasks have stopped until its impact is too great to ignore which it too late.
