Append a guarded snippet to /root/.bash_profile that forces TERM=linux on physical LXC consoles (e.g. noVNC) for login shells. This prevents readline (8.2+) from querying CPR (ESC[6n) which can produce stray R;80R garbage; the change runs only for non-SSH sessions and detects /dev/console or /dev/ttyN. The block is only added if a __cs_console_term marker is not already present.
