I'm not sure which name you're referring to. Is it the one in the [tracker] section of the tracker's config.ini? That's purely cosmetic AFAIK. The [rdbms] name can't be the one you mean as that would result in a database error. If it's the "name=tracker home" argument to the roundup-server command-line, please give me some hint as to how I could improve upon the help message:

How to use "name=tracker home":
   These arguments set the tracker home(s) to use. The name is how the
   tracker is identified in the URL (it's the first part of the URL path).
   The tracker home is the directory that was identified when you did
   "roundup-admin init". You may specify any number of these name=home
   pairs on the command-line. Make sure the name part doesn't include
   any url-unsafe characters like spaces, as these confuse IE.
