Help! passwd file corrupted

Help! passwd file corrupted
Hi,
I am new to UNIX, and have recently installed Suse 9.3. I have been experimenting with all of the commands and have somehow managed to modify the default shell of the root user to an invalid file. Consequently I cannot su to the root user as I receive the 'no such file or directory' error message.
I have attempted to use the rescue facility by booting from the installation CD, however it seems that the files that load appear to be from ramdisk. I have tried to mount various other devices without being able to locate the file in question to modify it.
If anyone has any solutions/experience/ideas I would be very grateful.
Thanks in advance.

did a big mistake, changing root entry of /etc/passwd to
root:x:0:0:root:/root:/usr/bin/tmux split-window -v \; attach
as expected, now I can't login as root anymore. sudo ed /etc/passwd etc. doesn't work.
Any idea?

quotaon
QUOTAON(8) BSD System Manager's Manual QUOTAON(8) NAME
quotaon, quotaoff -- turn filesystem quotas on and off SYNOPSIS
quotaon [-g] [-u] [-v] filesystem ... quotaon [-g] [-u] [-v] -a quotaoff [-g] [-u] [-v] filesystem ... quotaoff [-g] [-u] [-v] -a DESCRIPTION
Quotaon announces to the system that disk quotas should be enabled on one or more filesystems. Quotaoff announces to the system that the specified filesystems should have disk quotas turned off. The filesystem must be mounted and it must have the appropriate mount option file located at its root, the .quota.ops.user file for user quota configuration, and the .quota.ops.group file for group quota configuration. Quotaon also expects each filesystem to have the appropriate quota data files located at its root, the .quota.user file for user data, and the .quota.group file for group data. These filenames and their root location cannot be overridden. By default, quotaon will attempt to enable both user and group quotas. By default, quotaoff will disable both user and group quotas. Available options: -a If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable any filesystems with an existing mount option file at its root. The mount option file specifies the types of quotas that are to be configured. -g Only group quotas will be enabled/disabled. The mount option file, .quota.ops.group, must exist at the root of the filesystem. -u Only user quotas will be enabled/disabled. The mount option file, .quota.ops.user, must exist at the root of the filesystem. -v Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off. Specifying both -g and -u is equivalent to the default. Quotas for both users and groups will automatically be turned on at filesystem mount if the appropriate mount option file and binary data file is in place at its root. FILES
Each of the following quota files is located at the root of the mounted filesystem. The mount option files are empty files whose existence indicates that quotas are to be enabled for that filesystem. .quota.user data file containing user quotas .quota.group data file containing group quotas .quota.ops.user mount option file used to enable user quotas .quota.ops.group mount option file used to enable group quotas SEE ALSO
quota(1), quotactl(2), edquota(8), quotacheck(8), repquota(8) HISTORY
The quotaon command appeared in 4.2BSD. 4.2 Berkeley Distribution October 17, 2002 4.2 Berkeley Distribution
