Hello kind folks.
I recently upgraded to Bullseye Armv8 64bit version on my RPi 4 4GB. Since I wanted a fresh installation and migrate my data to the new installation, I first flashed the image on a separate USB stick. Once I ran the initial setup I then replaced the /boot and / partitions over my existing USB drive having the older Buster image.
Changed UUIDs to read partitions correctly, mounted the user data partition and setup all my dockers as well. Everything is setup up fine and running great. It was a relatively quicker setup than I had expected. 
The only thing now is I’m not able to see the MOTD message in the banner anymore and it’s showing this error instead:
curl: (23) Failure writing output to destination
On digging a little bit, I found that the /run/dietpi folder isn’t being created on boot, which is why the banner script isn’t able to find the MOTD message to display. On manually creating this folder, banner is correctly displaying MOTD. However, every time I reboot, the folder goes missing and isn’t created automatically.
On the other hand, the USB stick which has a fresh installation is able to do this fine. So I think I might have changed some permissions unknowingly somewhere. I did not create/write images of partitions when migrating, but had simply copied them over and changed some of the permissions where required.
Can somebody help in fixing this? Are there any other Dietpi scripts that rely on this path? I haven’t faced any other issues till now, but don’t know if something might be amiss in the background.
yes the directory should be created during boot process and it is used by a couple of scripts. can you check related service
journalctl -u systemd-tmpfiles-setup
systemctl status systemd-tmpfiles-setup
Looks like I didn’t check close enough. systemctl from dietpi user isn’t working:
Failed to connect to bus: No such file or directory
Here’s the output with sudo:
dietpi@nas:~$ sudo journalctl -u systemd-tmpfiles-setup

I guess some permission issues on Root Partition. Can you share following
ls -la /
And of course sudo to be used as non-root user.
Most systemctl commands will need root, but just systemctl should give some result as well right?
Output for ls -la /:

Yes if you use sudo 
Pls do following to fix the permission issues on root / directory
chown root:root /
chmod 755 /
reboot
Thanks for your help!
That worked fine. I missed checking / dir for permissions.
