I am using Debian for long time and really like it for stability. Recently I wondered if it is possible to run Arch Linux from chroot. I want to run full Wayland session from Arch. I found Archbox project and it is worked for me, but I couldn't start any Wayland compositor from tty (Error: can't connect to Wayland socket . ). How can I properly do this? Or maybe there is a better way than chroot?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You can use wayland in container but the easy way probably would require to give whole GPU to the container (but my knowlwdge is limited)
What I do know that this project is doing that: https://games-on-whales.github.io/
That also came up in search results that could help: https://unix.stackexchange.com/a/359244
Why I need a full isolated container? Can't I just use chroot?
Because you're relying on compatibility between older Debian software (systemd, etc) and newer versions installed in the chroot. Things get weird quickly.
Consider a nested privileged container instead (LXC or similar) and cross your fingers that Debian systemd and Arch systemd play nice.
If the above fails just make a VM and pass through the GPU with GVT-g (otherwise pass through the entire GPU.)
If all of that fails install Arch to a USB attached SSD or something.
What Systemd compatibility I need to run Graphics session?
