Description

uci-defaults scripts are essential for accessing device after firmware reset.

If user defined a custom UCI-Defaults script with OpenWrt Firmware Selector, it's feasible to preserve it upon firmware upgrade, at least optionally, and include it to new image.
Otherwise, access to the device can be lost next time user performs firmware Reset.

As a simple approach to solve this, luci-app-attendedsysupgrade/auc utilities could check if /rom/etc/uci-defaults/99-asu-defaults file exists in current firmware,
https://github.com/openwrt/asu/blob/3ef4757b9fcc401b3d18ebb6954276b0210f07fb/asu/build.py#L202
and if so, include it to a new image using "defaults" BuildRequest member:
https://sysupgrade.openwrt.org/ui/

BuildRequest {

defaults string Custom shell script embedded in firmware image to be run on first boot.

Research direction

Start with the luci-app-attendedsysupgrade/auc utilities and the referenced asu/build.py section around line 202. Inspect how BuildRequest handles the defaults member, then verify that an existing /rom/etc/uci-defaults/99-asu-defaults file is included in the generated firmware image and runs on first boot.
