Junbo-Zheng opened a new pull request, #21744:
URL: https://github.com/apache/nuttx/pull/21744
## Summary
Use `init_main` as the init entrypoint, with the console shell
started as an nxinit service from the `/etc/init.d/init.rc` baked
into the ROMFS -- the same arrangement the esp32s3 boards already
use after their "switch defconfigs to nxinit entrypoint"
conversions.
## Impact
- **Users**: the board boots through nxinit; the console NSH is now
a supervised service (restarted on failure, `restart_period`
1000 ms) instead of being the init task itself. The interactive
experience is unchanged.
- **Build**: the esp32 common ROMFS packing gains the init.rc entry
when `CONFIG_SYSTEM_NXINIT` is set; no other board changes.
- **Hardware**: esp32-m5-stickc-plus only.
- **Documentation**: None.
- **Security & Compatibility**: None.
## Testing
CMake build, flashed on an M5StickC Plus:
```
cmake -B build -DBOARD_CONFIG=esp32-m5-stickc-plus:nsh -G Ninja
cmake --build build -j
```
```

```
`reboot` comes back to the same state: init_main respawns the
console service from `/etc/init.d/init.rc`.
