Attended Sysupgarde with custom partition size

Installing and Using OpenWrt
1

Hi there.
So, finally i'm updating from 22.03.3 to 22.03.5 and have one question regarding attended sysupgrade.
For my two Archer C6 i just used the sysupgrade image and everything went fine.
My main router is a FUTRO S920 though and i installed it with a custom image with bigger rootfs because i planed to run HA on it:

root@OpenWrtMain:~# df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 4.0M      4.0M         0 100% /rom
tmpfs                     3.7G      1.2M      3.7G   0% /tmp
/dev/loop0                2.0G    221.9M      1.8G  11% /overlay
overlayfs:/overlay        2.0G    221.9M      1.8G  11% /
/dev/sda1               126.0M      5.2M    118.2M   4% /boot
/dev/sda1               126.0M      5.2M    118.2M   4% /boot
tmpfs                   512.0K         0    512.0K   0% /dev

I probably won't do that anymore, so i guess i technically don't need the bigger partition anymore (although of course it would be nice to keep it!).

I'm unsure now if the attended sysupgrade with asu will work in my case and just reduce the size to default or if i have to expect some issues? I only found this thread that doesn't really clear up things for me tbh ^^

So my core question is: can i use attended sysupgrade without too much of a worry or would it be better to read into the image builder stuff again and build a new custom image? (and of course this time better document what i did with it -.-)

In the latter case, i'm also a bit confused because the output of the imagebuilder doesn't generate a ...sysupgrade.bin like is available for the C6 - so should i just use the same image as for installation? Or the ...-generic-kernel.bin? Or does that not work with LuCI and keeping the config?

Thanks in advance!

I've asked aimilar queation today and the answer was that the juat the size will reduce https://forum.openwrt.org/t/cyberoam-cr25ing-cr25wing-wired-router-hw-discovery/137252/7

Thanks for the answer - though that doesn't specifically cater towards attended sysupgrade but to flashing a sysupgrade.bin file...or am i missing something in that thread?

Ultimately it is the same. Asu is genereting automaticaly the correct file and uploads it directly.

I just tried it via Wireguard as I am out of home.. I lost connection, so one is for sure- packages gets wiped. Do not know about the rest- but be carefull.
Kind regards
