The Ingenic T40N cameras were losing overlay configuration changes (password, timezone, etc.) when rebooted through the WebUI. This occurred because the WebUI reboot was bypassing the proper shutdown sequence that ensures overlay filesystem synchronization.
Root Cause
The issue stemmed from the WebUI calling
reboot
directly, which in busybox systems defaults to a forced reboot that skips the normal shutdown process. This prevented the overlay filesystem from being properly synchronized before the reboot, causing configuration changes stored in the overlay to be lost.Solution
Added a reboot wrapper script at
/general/overlay/usr/bin/reboot
that:-f
)rcK
shutdown scriptTechnical Implementation
The wrapper script:
/usr/bin
before/sbin
) to intercept reboot calls-f
(force),-n
(no sync),-d
(delay)Example Behavior
This ensures that configuration changes made through the WebUI are properly persisted across reboots while maintaining backward compatibility with existing scripts and system operations.
Fixes #1880.
