If you're going to change the header right now, then I would think it is best to add a field for version number. What you're saying is that "we will never ever have to change this format again", and that seems overly optimistic to me. I don't even know what this *IS*, other than you report that this change will cause "weird and unfortunate things to happen" for backing files created with the previous format. Any format where a change can cause "weird and unfortunate things to happen" should have a version number in it, in my opinion... What downside is there to adding a field for version number? --- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or drosih@rpi.edu Rensselaer Polytechnic Institute To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
