I have a really stupid trouble: on a Redhat 9.0, the line matching the root 
account in the file /etc/passwd has been changed from ".../bin/bash" to 
".../sbin/nologin". We have the root password, but when performing a "su" 
command, the system replies that the account is not currently available.

So the question is: how from an user's account and knowing the root's 
password but having the root account disabled can we reactivate this root's 
account?

Any suggestion would be appreciated, I do not want to reinstall the box :(

Get tomsrtbt [1], Knoppix [2] or some other bootable distro. Boot it,
mount your machine's root partition and edit $MOUNTPOINT/etc/passwd to
reset the login shell.
