I have a root account from which I do all of my tasks. I set up my partitions to mount at startup. I have also created an account for my younger brother. I do not want him to access specific partitions, while still having access to others.
I have:
- sda5
- sda6
- sda7
I want to block access to sda5 but want to give him permission to access the other sda partitions. How can I do that?
