Can the device names for hard drives be forced before root is mounted in so much so that udev rules can force via a device serial number to be a specific /dev/sdX device name. Looking at my pci and bios boot order I shouldn't even need to do this but I think the defaults of udev or the sysfs?? are to move USB devices to latter drive letters. I am booting from a USB 16GB flash drive and would prefer the device be sda but even if I could force it to be sdz, and force my sata drives to be specific drive letters based on their serial numbers so that I can create a hotswap raid array and be confident that once my drives are installed they won't move around to different device names. I think this information would be useful to a lot of people who have simply given up in the past, and after weeks I was at the point of giving up but Greg's email bot has given me one more ounce of juice to keep trying. I really would prefer to not bother him directly but I have a sneaking suspicion what I'm trying to accomplish isn't possible. I have this thread: http://ubuntuforums.org/showthread.php?t=2202219 on Ubuntuforums.org where I'm trying to find out if this is possible: I really appreciate any help, and please forgive my demeanor in my thread on the ubuntuforums page I have a personality that takes an acquired taste. If there is any information needed that I haven't provided in the post at the link above please let me know and I would be happy to provide it. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
