While there may be a passing resembelance of Linux device names to what you think a device should be named based on how you plugged in various cables, don't expect those to stay the same or be consistent. Doing so, you _will_ get bit some day. Use characteristics intrinsic to the device itself (labels, mac addrs, ...) rather than some perceived topology, and you'll be much happier in the long run. -- Matt Domsch Linux Technology Strategist, Dell Office of the CTO linux.dell.com & www.dell.com/linux -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
