@lkundrak do you have any suggestions/thoughts about this?

@nullr0ute I just checked the 40network module, and it does the decision between network-legacy and network-manager, based on /usr/libexec/nm-initrd-generator. But there is no RPM that provides that binary in either Fedora 29 or Rawhide at this moment.
So I am guessing that that path might be wrong, or it depends on something that's not in Fedora yet?
Both 35network-manager and 35network-legacy return 255 from their check() functions, which mean they get selected if something depends on them.

The relevant code from 40network/module-setup.sh:

depends() {
    echo -n "kernel-network-modules "
    if ! dracut_module_included "network-legacy" && [ -x "/usr/libexec/nm-initrd-generator" ] ; then
        echo "network-manager"
    else
        echo "network-legacy"
    fi
    return 0
}

My understanding is, that without nm-initrd-generator no kernel cmdline parsing by NM is done, so, as soon as NM is ready, that file will be provided.

Oh, and btw, network-legacy refers to dracut network-legacy and not to initscripts network-scripts.

So we're seeing a regression in network related stuff in recent versions of dracut if there's no network link and I'm not sure why that is then.

@nullr0ute what is the kernel command line? rdsosreport.txt with rd.debug enabled?

Kernel command line is:
[ 0.000000] Kernel command line: BOOT_IMAGE=/ostree/fedora-iot-578355f971db3df3e514998aa6fc506bc0d99aabecff5694337fd45686ee7678/vmlinuz-4.18.16-300.fc29.aarch64 net.ifnames=0 modprobe.blacklist=vc4 root=UUID=953c1a31-ccad-4ca3-815a-585f34204601 ostree=/ostree/boot.1/fedora-iot/578355f971db3df3e514998aa6fc506bc0d99aabecff5694337fd45686ee7678/0

I don't see any ip= arguments here.. so no network in the initramfs
