out of principle, i wonder if there is a way to have privacy between accounts. if users have the ability to escalate to root privileges (to install applications for example), they could also view the personal files of other accounts via a file manager. is there a way to prevent this while still using the same system? permissions for each user folder is irrelevant with root privileges. per-user encryption would work for debian/ubuntu, but what about fedora? it encrypts the whole home directory (even without use of LVM).
