Seems to be a bit of a problem on R2S, am I the only one?
I expanded of the second hide partition f2fs of the squashfs filesystem on the VM,
form this
https://forum.openwrt.org/t/howto-resizing-root-partition-on-x86/140631,
but on R2S after reboot it won't start.
Since I don't know how use the serial port to debug R2S, I can't get the startup logs
fsck.f2fs -f ${LOOP}
+ fsck.f2fs -f /dev/loop1

I made several attempts and I noticed a lot of modifications on resize.f2fs,
tried fsck.f2fs again after resize.f2fs and got a Checkpoint is polluted error, which I think should have failed.
I tried using the tune2fs method. Stuck in resource busy when remount.
mount -o remount,ro /
Is there any way to fix this?
Thanks
Update 1:
The reason I seem to have discovered is that those built using firmware selector will use ext4 as the overlay,
same as this [https://forum.openwrt .org/t/resizing-the-hidden-overlay-filesystem-when-it-is-ext4-and-not-f2fs/140490](https://forum.openwrt .org/t/resizing-the-hidden-overlay-filesystem-when-it-is-ext4-and-not-f2fs/140490),
and when I use imager-builder on my windows wsl, it will use f2fs as overlay.
