Is it possible to run some application in the chroot or container but allow DBus interaction with host system?
Solution 1:
Check out the following guide on how to
- create a system container with some old version of Ubuntu (like 12.04 or 14.04), and
- set it up so that you can run GUI programs from within that system container and get the output on your host
See guide from https://blog.simos.info/how-to-easily-run-graphics-accelerated-gui-apps-in-lxd-containers-on-your-ubuntu-desktop/ .
The guide has an example on running some old Tcl/Tk utility in a Ubuntu 12.04 system container.
