USB drives and device names

It looks like there's some sophisticated stuff under /etc/usb/
that'll do anything you can imagine, but if all you want is to
ensure that a particular USB-resident filesystem gets mounted on
the correct mount-point regardless of what its device name is,
you could (assuming it's one of the filesystems that support
labels like the ext[23] filesystems do) create an /etc/fstab
entry that looks something like this:

   LABEL=myUSBdisk /mnt/someDir ext3 defaults,errors=remount-ro 0 0

...and then label that filesystem accordingly thus:

     /sbin/e2label /dev/sdc1 myUSBdisk  #ASSUME: filesys currently on sdc1

...after which this should "just work":

   mount /mnt/someDir

...even if your disk wanders around in the SCSI namespace.
