After a further investigation, I found many issues:

• the ABRoot files hierarchy is not supported (can be fixed with proper arguments during the build process)
• libudev.so.1 is not being loaded despite available in the system
• the snapd installation is missing some files in the apparmor profiles path

since this will take more time, I'll postpone the task after the stable and disable that option in the First Setup.

Hey! Mirko, you is able to see a solution for that?

ABRoot now supports systemd during the transaction but snapd need to be repacked to change the original snaps installation path since the root is too small.
