Sysupgrade on X86 with combined ext4 root

Installing and Using OpenWrt

What is the proper process of sysupgrading an generic X86 image with combined ext4fs root fs?

Every time I do sysupgrade, it wipes all the settings.
Embedded Wifi-routers don't seem to do that. They are able to keep settings.

So what would be the correct process to keep /etc when I have only one RW partition?

/dev/root on / type ext4 (rw,noatime)
/dev/nvme0n1p1 on /boot type vfat

It is annoying to update an headless X86 device that always resets to default.

Tried the squashfs image instead?

and what exactly is /dev/root, post fdisk -l ?

I have a combined ext4 image and I upgrade via the GUI with keeping settings.

root@X86:~# df -T
Filesystem           Type       1K-blocks      Used Available Use% Mounted on
/dev/root            ext4          253800     90212    158348  36% /

/dev/sda1            vfat           16334      6610      9724  40% /boot

root@X86:~#

I make my own builds but otherwise use OWUT to upgrade.
Make sure you have set the proper root fs_size beforehand if you changed that see:
