If you want to use these features for security, access them manually. But, OP said they are kind of a noob. Telling them to just use containers is dangerous and leads to false assumptions.
You are absolutely correct. I should have stated explicitly that I didn’t mean docker and/or using pre-built container images. I was talking about something like systemd-nspawn. And you are right that I should not have brought this up in this context. I will edit my original comment.
Great, I accidentally deleted my original comment because the Lemmy web interface doesn’t ask for confirmation when you click the delete button. And the buttons are so small on mobile that it‘s really easy to click the wrong button.
