Nasty config loss bug

Description

On two different ar71xx devices (different manufacturers) I have experience a nasty configuration loss bug.

The systems are that files in /etc/config are back to defaults but mount and df show overlay mounted on root (and /overlay has the right data).

reboot and firstboot have no effect. The only thing that works is failsafe, mtd erase rootfs_data, and then restore from backup.

Note that these is a custom builds with with procd-jail in use. I suspect an issue with jail mounts and symlinks like /etc/resolv.conf to /var which (as usual) is symlinked to /tmp and/or symlinks to /tmp when included in jail mounts.
