832KB available, 140KB free on Archer C6 (OpenWrt 24.10.0)

I did a Luci sysupgrade on my EU/RU Archer C6 using the official .bin with zero custom changes. The only box I checked before the upgrade is the one on logging the list of installed packages. After the upgrade, I ended up with only 140KB free, which leaves no room for two extra packages I had on OpenWrt 23. Is this normal? If not, what could I try to address it?

Filesystem                Size      Used Available Use% Mounted on
/dev/root                 4.5M      4.5M         0 100% /rom
tmpfs                    59.2M    244.0K     58.9M   0% /tmp
/dev/mtdblock5          832.0K    692.0K    140.0K  83% /overlay
overlayfs:/overlay      832.0K    692.0K    140.0K  83% /
tmpfs                   512.0K         0    512.0K   0% /dev

Download package list and sysupgrade again. should be 200-300kB in default config, not 700
One easy space saver is substitute wpad-xxx to hostapd-xxx or wpa-supplicant-xxx , ie if you need wifi client or access point.
Probably add luci-app-attendedsysupgrade to avoid mistake of installing packages with no space.

Yeah, it was my bad. It's between 200-300 after a sysupgrade. The rest came from attempting to install luci-app-sqm, which couldn't be completed because its dependency, pkg iptables-mod-ipopt needs 920, and there is only 140k available after the rest. How did it work through the prior OpenWrt versions though?

Sysupgrade again with clean image.
Try qosmate, it does not need iptables (but keep attendedsysupgrade handy if space grows)

After downgrading to 23.05.5, I see that the total space it provides is 1.31 MB, whereas the 832KB of 24.10 is not enough for qosmate with its dependencies either. Searching for a firmware upgrade via attended sysupgrade from 23.05 finds nothing.

If you click advanced mode you can add individual packages to squashfs.

I went the route of https://firmware-selector.openwrt.org/ and added luci-app-sqm to that. Only 332KB left after flashing, but I can live with it for now. Thanks for the tips!
