But /dev/sdX doesn't always work, because, for instance, my usual /dev/sdb 
was slow to respond on my last boot, and currently appears as /dev/sdf, 
with sdb/c/d/e being my (multi-type) sdcard, etc, adapter, medialess.

Tho if /dev/disk/by-*/* works, I could use that.  Tho AFAIK it's udev 
that fills that in, so udev would be necessary.
