CHAOS progressive terminal enhancement

[techtonik]

Linux terminal is a complicated beast. The state machine if full-fledged terminal is scary. That's why it needs to be decomposed into simple parts. Starting with most simple.

Story: Running mc in a fresh container

$ mc
The TERM environment variable is unset!
$ export TERM=dumb
$ mc
Your terminal lacks the ability to clear the screen or position the cursor.

This is Linux container, I connected to it using lxc exec c1 bash.

• [ ] how lxc connects to container - which streams, how are they connected, where redirected?
• [ ] what is terminal here?
• [ ] how lxc provides terminal? or who provides it, and what is lxc role?
