It is the daemon that is causing the problem.
This results in crashing the unetmsg service on these builds.

In /usr/sbin/unetmsgd:

Lines 21 uses SYSTEM_OBJECT_ACL.

function update_acl() {
	let data = ubus.call(libubus.SYSTEM_OBJECT_ACL, "query");
	core.acl_set(data.acl);
}

That came with commit 8e122f1 
(https://github.com/jow-/ucode/commit/8e122f16327c59b178468c7aa53a36e31ced970c)
into ucode and that into openwrt-24.10.

ufp also works without unetmsg installed, at least for my use case, so i 
forged my patch that way.
What are your concerns if we leave unetmsg out of ufp?

Thanks in advance!
