I have Ubuntu Intrepid installed in my desktop. While tweaking the /etc/fstab file for performance, I screwed up something and hence could not login to the Graphical Interface on reboot. I tried the Ubuntu LiveCD to access the system ( using the View Ubuntu without installing option) . I opened the terminal, entered the following command:
# sudo nano /media/disk-1/etc/fstab
Changed the file and saved.
System did not ask for a password anytime. I checked the file permissions for this file and found only root has access to change it.
-rw-r--r-- 1 root root 656 2009-01-10 23:35 fstab
To my surprise, I am able to access, modify or delete any file in the system through this LiveCD login (as user 'Ubuntu') without any access restriction !!!
Is this normal behaviour ? If yes, I find it as a security breach as one can access any system if armed with a LiveCD ???
Excuse me if this question is naive, I am a newbie to Ubuntu
