I wonder whether there is a way to make my ubuntu read-only when I mount it on another linux system. Let me clear what I want. I have a usb stick on where my ubuntu is installed. However, the problem is that I am able to change the files or folder on it by mounting it another ubuntu. How can I preserve it?
Thanks...
Edit: Guys thank you to all for your attention. However, I should add this information that I am not able to make any changes on the linux system onto where I plugged my ubuntu usb stick. This is why I have to do something on my ubuntu.
