The status field in the new BosConfig entry is set to Run, and the process starts running on machine name. See section 2.1.1 in the Reference Manual for more information on the BosConfig file. The recommended names, and those specified in the AFS Installation Guide, are buserver for the Backup Server process.
Legal values are simple, fs, and cron.
Also consult the entries in chapter 9 in the Reference Manual for runntp and upclient, as well as the AFS Installation Guide and the chapter on process management in the AFS System Administrator's Guide. For the fs-type process, this should be three complete pathnames to the binary files for the File Server, Volume Server, and Salvager, along with any command options. Surround this parameter with quotes or other delimiters if it contains spaces. The second parameter specifies the time at which the BOS Server is to execute the command specified by the first parameter. Specify either a day and time or a time alone.
