This must be a semantic issue since alpha uses nothing but 'dangerously > dedicated'- at least in terms of how to use disklabel to create a usable disk > on FreeBSD alpha. It is kind of semantic. However, on the alpha it is hardly dangerous. Nor do we fake a MBR on the alpha (which is what makes it dangerous). The alpha architecture doesn't use MBR's, but the PC arch does. Thus, having a disklabel on the alpha is normal, having one at the start of a PC disk requires ugly hacks that break the PC arch, hence the difference. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
