Improve the InnoDB recovery function: support multiple table spaces

Improve the InnoDB recovery function: create a separate my.cnf for the server instance that performs the recovery on the snapshot, including the InnoDB-related parameters from the main my.cnf file (particularly table spaces, log files) as well as other options (e.g. sane buffer sizes) (Maybe the script could just parse the original my.cnf file for the related options and add these to the mysqld_safe call?)
