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.

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.
