Well, since this is the -current list... have you updated recently? There were some recent changes by PHK to the dump format that may have broken/fixed things, if your answer to that question is yes/no, respectively. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
