X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 12 Oct 2010 18:51:00 -0000 For some reason the /dev/ufs/label entry that geom creates for every UFS formatted partition is deleted when the device is mounted. This is not the case for other file systems, though I have not tried them all. It makes the drive much harder to deal with when you have to keep track of which physical drive contains the labeled media. It is a particular issue for hald and the tools which depend on it. Is there a good reason for this odd behavior of UFS? If there is not a good reason, could it be changed? -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
