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.
If you are not sure, or forgot something, hit Control-C now or

The script made it to the end, that looks good. Before you logout do some
sanity checks;
1. Can you still login as a normal user.
2. Login on another virtual console, network or whatever as user 'mbse'.
Then type 'echo \$MBSE_ROOT'. Does this show the path to
'$MHOME' or nothing.
3. Login on another virtual console as user 'bbs'. It should not ask for
a password, but should direct try to start the bbs. This is not
installed yet but you should see error messages and then be logged out.
If these three tests weren't successfull, restore /etc/passwd and
or /etc/shadow, the backup copies have the extension '.mbse'.
