Probably not, but this could easily be worked around by using a symlink in /dev/disk/by-uuid. The only problem is that there may not be one for sdX; at least I don't have a symlink to /dev/sda in /dev/disk/by-uuid, , only symlinks to /dev/sdaX, i.e. the partitions. > The original poster doesn't mention the verson of Debian, Squeeze uses > uuid's, > and if you are using external usb devices, uuid's are a great way to make > sure the same file system gets mounted appropriately each time. Maybe the disk name in /dev/disk/by-id could be used instead, there are symlinks to /dev/sda on my system.
