Subject: [PATCH] Updated the docker init-script to not re-install MySQL; it
 can cause more trouble than it might save; added a guard against trying to
 set up the ietf database if MySQL isn't running; and changed the final
 working directory to be the same as where the user invoked the 'docker/run'
 command.  If not started via docker/run, drop into the home directory.  -
