Bug Description

If you have a UEFI system with Arch Linux installed, then add a Ubuntu system in Multi-boot the initrd line is wrong for Arch Linux.
Ubuntu 30_os-prober adds "initrd /intel-ucode.img" and Arch fails to boot.
Arch requires that line to be "initrd /intel-ucode.img /initramfs-linux.img" to boot.
This happens every time a new Ubuntu system is added to a PC with Arch Linux.

This is easily verifiable. Have Arch Linux installed and add any Ubuntu version to your system. Take a look at the /etc/boot/grub.cfg file. You will see that /initramfs-linux.img is missing and also you will not be able to boot into Arch. The only way to boot Arch is via the fallback kernel.

Isn't this against os-prober? It was on openSUSE.
