Yes (on amd64, arm64 and armhf).

I do not see the error in the systemd PID 1
except on an armhf kernel with CONFIG_BPF_JIT_ALWAYS_ON=y.
But we do not need to consider the issue on the armhf kernel here.

Yes.

This seems something like "Permission denied" or "Operation not permitted",
but the error is "Invalid argument", which seems strange.

Currently, to trigger this issue, I need task-xfce-desktop (on every arch.).
I believe that this can be reproduced without task-xfce-desktop,
and will try to find a reproduction procedure with CUI in a weekend...
