I just discovered something that I wanted to bring to your attention, because I don’t really know how or why this happed but is nevertheless remarkable.
I dicovered it by accident by doing a search in my dietpi-backup and suddenly a cascade of symlinks showed up in my results, looking like this
du: cannot access '/mnt/backup/data/bin/X11/X11/X11/X11/X11/X11/X11/X11/X11/X11/X11/X11/X11/X111 etc.
So I checked /bin and found a symlink looking like this:
lrwxrwxrwx 1 root root 1 15. Feb 2021 X11 → ./
link creation is Feb 2021 but
I just recently installed MATE and RealVNC server and used the Pi headless before.
I have deleted the link now.
Thanks for the Wiki link.
As i googled it first hits were
SB Chiemgau Traunstein,
Sensotronic Brake Control,
Session Border Controller,
Southwestern Bell Corporation
Ok. I hope it doesn’t create problems with backup to ozher machines. I discovered the cascade on my nas (openmediavault) where I am not sure now wheter it copied the symlink or replaced it by another copy of usr/bin.
I just rember having a cascade of X11 folders.
So there might be a potential for error.
