Maybe this is what the OP is looking for: https://lists.freebsd.org/pipermail/freebsd-stable/2013-January/071851.html I too recommend some form of labels, be it GPT, UFS, or glabel. -- +-------------------------------+------------------------------------+ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +-------------------------------+------------------------------------+ From owner-freebsd-questions@freebsd.org Mon Jun 26 23:02:26 2017 Return-Path: <owner-freebsd-questions@freebsd.org> Delivered-To: freebsd-questions@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 46391D93CC6 for <freebsd-questions@mailman.ysv.freebsd.org>; Mon, 26 Jun 2017 23:02:26 +0000 (UTC) (envelope-from matthew@FreeBSD.org) Received: from smtp.infracaninophile.co.uk (smtp.infracaninophile.co.uk [81.2.117.100]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "smtp.infracaninophile.co.uk", Issuer "infracaninophile.co.uk" (not verified)) by mx1.freebsd.org (Postfix) with ESMTPS id 771DB6E293 for <freebsd-questions@freebsd.org>; Mon, 26 Jun 2017 23:02:24 +0000 (UTC) (envelope-from matthew@FreeBSD.org) Received: from liminal.local (unknown [IPv6:2001:8b0:151:1:1c1d:86a1:a200:b700]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) (Authenticated sender: m.seaman@infracaninophile.co.uk) by smtp.infracaninophile.co.uk (Postfix) with ESMTPSA id 4C1C0CB4A for <freebsd-questions@freebsd.org>; Mon, 26 Jun 2017 23:02:03 +0000 (UTC) Authentication-Results: smtp.infracaninophile.co.uk; dmarc=none header.from=FreeBSD.org Authentication-Results: smtp.infracaninophile.co.uk/4C1C0CB4A; dkim=none; dkim-atps=neutral Subject: Re: Shift ada device numbers?
