The detected $OSTYPE distribution is $DISTNAME $DISTVERS Everything looks allright to start the installation now. Next the script will install a new group 'bbs' and two new users, 'mbse' which is the bbs system account, and 'bbs' which is the login account for bbs users. This account will have no password! The shell for this account is the main bbs program. One final important note: This script will make changes to some of your system files. Because I don't have access to all kinds of distributions and configurations there is no garantee that this script is perfect. Please make sure you have a recent system backup. Also make sure you have resque boot disks and know how to repair your system. It might also be wise to login as root on another virtual console incase something goes wrong with system login. Darwin (OS X) Users must install the .dmg image of user utils available on Version Tracker and within this archive prior to continuing the installation.
