How do system user id numbers get determined in RHEL?

Solution Verified - Updated -


  • When installing the mysql-server rpm, it adds a mysql user to the password file on the machine with a uid of 27.
  • Is there a registry of these system id numbers?
  • When creating an rpm that has to add a system user, is there a range that we should use so that we wouldn't conflict with the uids in the rpms from Red Hat?
