Dirpref is not something which is "enabled" or "disabled", not in the same sense as softupdates is "enabled". Dirpref is a smarter layout of information in a partition. You need a version of the system which knows HOW to do that smarter layout, and then you just rebuild the partition. There is no switch to turn on and off. -- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
