Hi Juergen,
Thank you for point out that the boot message on the previous mail was garbled.
So re-send it again the email with the attachment of the boot-up message log.
As of this writing, I observed that when I do clean reboot the system (by
typing reboot command in the terminal) the deleted files will not restore in
the mounted spare partition. But if I do power reboot by flipping the power
switch, the issue will surface.
It seems to me it is a partition safety mechanism in the event of power failure
(e.g. rebooting the system through power supply).
Anyway, I will leave the comment from the expert about my observation.
Best Regards and have happy holidays!Ian

Subject: Re: [oselas] u-boot_hd.config
Hi Juergen,
I am currently in use the spare partition for saving some application. One
thing I noticed that when I delete a file and reboot the system, the deleted
file will automatically restore.
Any idea why it did happen?
Here is the boot up log for reference:[ 1.886867] systemd[1]: /etc/mtab is
