you asked the same already:

I replied asking for more information:

Also the system logs you presented seem to be lacking any specific
error for the weston service unit. I can't say if that is for real, or
if you just trimmed it out of the logs.

Are you familiar with
https://gitlab.freedesktop.org/wayland/weston/merge_requests/39 which
attempts to document how exactly to launch weston from a systemd system

I never intended that to be used with the root user though. I have no
idea what running it as root would imply, but I would avoid it if at
all possible.

Since it looks like Weston gets killed by SIGTERM, I would think that
something outside of Weston is killing it deliberately.

Is /usr/bin/weston the actual weston executable or some wrapper script?

Does enabling session lingering work around the problem?
