Overlay filesystem is still a disaster

Have tried to use it many times since the early days of EasyOS in 2017. Here are recent posts:

I have remained hopeful. After all, other Linux developers are using Overlay, so why is it so awful for me? Yesterday, I compiled the 5.15.149 kernel, and this time ticked all these boxes:

Booted, but Xorg failed:

(EE) 
Fatal server error:
(EE) Cannot move old log file "/var/log/Xorg.0.log" to "/var/log/Xorg.0.log.old"

So many basic operations fail. For example, cannot do a recursive remove:

# rm -rf /var/log
rm: cannot remove '/var/log' directory: not empty

Cannot move:

# mv -f /var /varBAK
mv: cannot move '/var' to a subdirectory of itself, '/varBAK'

Try remove a folder that has files in it, and no sub-directories:

# rm -rf /root/Web-Server

...removed the files, but not directory 'Web-Server'

I tried various combinations of turning off those default options, still got the same failures. At least didn't get that "invalid cross-device link" from previous tests.

I just have to give up. When Dr. Okajima retires from developing Aufs, I will also retire from Linux development.
