Thanks for this contribution! 👍

Quick question: What is this supposed to achieve? I don't think this would transpire into user's Bash environments (need to edit ~/.bashrc for that). Are you fixing some graphical RUN command in another Dockerfile?

Also, please note that we already attempt to set DISPLAY=:98 via /etc/environment 4 lines above, but it doesn't seem to work for Bash sessions on Janitor. Maybe we need to stop using /etc/environment and move everything into the user's ~/.bashrc?

Follow-up thought: We're heavily customizing ~/.bashrc to make Janitor work on Bash, but this doesn't work for ZSH, Fish, etc. Maybe we should move all Janitor-related ~/.bashrc customization into a dedicated ~/.janitorrc file, and source that file in ~/.bashrc, ~/.zshrc, ~/.fishrc etc?

./mach run still doesn't work, and it does heavily annoy me having to go to VNC to run it there :)

Understandable! Sorry about this frustrating caveat.

Please export the DISPLAY variable in a common ~/.janitorrc script, and source this script in ~/.bashrc. (Using ENV in the Dockerfile won't solve the problem I think.)
