Hm, this is very strange.
Block devices such as /dev/sd? are directly created by the kernel and
made available via devtmpfs. Mounting /proc and /dev is one of the first
things done in
/usr/share/initramfs-tools/init
way before systemd-udevd is started.
If you have no block devices at all, I'm at a loss what's going wrong.

The devices in /dev/disk/by-?/ are symlinks pointing at the real
devices. Those are actually created by udev.
