Unless there is a good reason to do otherwise, you may want to
unconditionally use the File.dirname(__FILE__) trick.  There are plenty
of other ways for that Start in option to be busted where it isn't set
to the root directory of a drive.  I suppose the way Ocra works may
complicate things there though.

Another option would be to add an argument for the script that would
specify the log directory.  You could make that argument optional by
falling back to the File.dirname trick if the argument isn't specified.

BTW, you might want to try doing File.dirname($0) instead of using
__FILE__ here.  I think that may work as you would expect even with Ocra.
