Does multi user posix really get much use still? And should it? The model is how old now and we're still finding vulnerabilities more or less by design. Computers are so cheap that almost everyone has one in their pocket, and most in the first world own 2-3. Multi user operating systems just don't seem relevant anymore.
- jimrandomh 5y agoYes. One use case is application sandboxing; the users aren't separate people, but separate programs. Eg on Android, each app is a "user", and Linux filesystem permissions are used to control what the apps can do. But there are also a few instances where you still see the different-users-ssh-into-the-same-server model; for example that server might be controlling a cluster, and have users ssh'ing in to do otherwise-slow computations.
