Env vars are not secure. Anything that has root access can see all env vars of all applications via /proc.

(And modern Linux is unusable without root access, thanks to Docker and other fast-and-loose approaches.)

How often do you log in as root, or use sudo to become root, when you're working with Docker containers?

Because I never do, unless I'm down in the depths of /var/lib/docker doing stuff I shouldn't.

That just means you outsourced the `sudo` invocations to some other person. (Which is even worse.)

[ErroneousBosh]

No, it means I understand how Unix permissions work.

Glib response, but in reality you basically cannot do anything in a modern Linux system without root except read and write files in your home directory.
