# chmod 755 /
What you should be worried about is how your system got into this state
in the first place. Any ideas on how someone running as root could
change the permissions of the root directory so that any regular user
could create, delete and rename files there? For instance, on your
system a regular user could run the command "mv /lib /trash" and
completely break your system in a way that would be quite difficult to
recover from.
