  yes, i'll be testing as root, so i assume i can skip that "GRANT"
step.

  i'd seen a number of solutions that did that last part in two steps:
dump the db to a file, then run mysql as a separate command.  so
there's nothing wrong with using a pipe and driving the output to the
input?  good.  i thought that was acceptable, i just wanted to make
sure.

  of course, all will be backed up thoroughly. :-)
