[Solved] How can I create a system recovery OS based on the archiso?

There are instructions on the wiki for making a recovery OS using grml, but I'd like to make one based on the Arch Install ISO, as it's a little more comfortable to me.

I know I can create one with the `archiso` tool, but I'm not sure how to get it to boot with a systemd-boot entry. I extracted the vmlinuz-linux, initramfs, and airootfs.sfs from the ISO, and put in in /boot/rescue, and added this systemd-boot entry:

title   System Rescue
linux   /rescue/vmlinuz-linux
initrd  /rescue/initramfs-linux.img
options apm=power-off boot=live live-media-path=/rescue/

This unfortunately fails to boot though:

  
:: Mounting `/dev/disk/by-label/` to `/run/archiso/bootmnt`
Waiting 30 seconds for device /dev/disk/by-label/ ...
ERROR: `/dev/disk/by-label` device did not show up after 30 seconds...

So, what files should I move to /boot/rescue, and what should I put in my systemd-boot entry?

Re: [Solved] How can I create a system recovery OS based on the archiso?

I do have extracted files in folder "/EFI/ArchISO":

/boot/EFI/ArchISO
├── initramfs-linux.img
├── vmlinuz-linux
└── x86_64
    └── airootfs.sfs

My EFI partition have label "EFISYS".
Loader entry file "/boot/loader/entries/archiso.conf":

title    Arch Linux
version  archiso
linux    /EFI/ArchISO/vmlinuz-linux
initrd   /amd-ucode.img
initrd   /EFI/ArchISO/initramfs-linux.img
options  archisobasedir=EFI/ArchISO archisolabel=EFISYS copytoram
