I had the impression that namedev in udev had persistent naming support which has there to solve precisely this kind of problem. udev does indeed support persistent naming, but with the latest version of udev, it doesn't appear there's integrated support for USB mass storage devices; will have to check with the developer to find out what the plans are for integration of mass storage devices. Fix summary typo. There is no "out of the box" persistent naming scheme in udev. It just creates the nodes with the name the kernel suggests (with some minor renames). Users can create their own rules/naming scheme easily. http://fedora.redhat.com/docs/udev/ http://www.reactivated.net/udevrules.php |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040809 Epiphany/1.3.8 Description of problem: In discussion in fedora-list (kernel-2.6.9-1.6_FC2 boot failure where kernel-2.6.9-1.3_FC2 works) I illustrated that device naming sd{a,b} depends on plugging order. I'm told that this is actually a bug. My test equipment is a Pentax Optio 33 LF digital camera that presents as a USB disk a USB2 disk enclosure containing a 40 Gb Laptop disk drive. an HP Evectra Pentium III, Nahant-1 DT Version-Release number of selected component (if applicable): 030-26 How reproducible: Always Steps to Reproduce: 1.Insert camera & power on 2.Insert disk 3.View their device names 4. Unplug both 5. Insert disk 6. Inser camera & power on 7. View their changed device names Expected Results: That the camera and disk drive would have the same device names at steps 3 and 7. Additional info: See the above-mentioned thread. Note that I've not discovered any documentation on setting up udev and so it's as installed. Note that applying updates to this system is difficult. I do, however, have FC3 and Nahant-2 (AS) systems.
