rEFInd: how to boot an image on another partition [solved]

How can I direct a rEFInd menuentry to boot image files that reside on another partition?

Example:

sda
 |--sda1 vfat (efi partition)
 |--sda2 ext4 (boot)
 |--sda3 btrfs (root)

I don't want to copy my kernel images to my efi partition (sda1).  I want them to stay on my "old" /boot partition (sda2).  How can I modify the following refind.conf entry to reflect this?

menuentry "Arch Custom" {
  icon EFI/refind/icons/os_arch.icns
  ostype Linux
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom.img
  options "root=/dev/sda3 rootfstype=btrfs rw systemd.unit=graphical.target"
}

I know this is possible because the autodetection option in rEFInd does it automatically tongue  Thanks!

Copy the ext4 EFI driver from /usr/share/refind/drivers_x64/ext4_x64.efi to <EFISYS>/EFI/refind/drivers_x64 and then use the following config

## Specify location of EFI drivers dir for rEFInd to autoload it
scan_driver_dirs EFI/refind/drivers_x64

menuentry "Arch Custom" {
  volume <FS LABEL of the sda2>
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom.img
  options "root=/dev/sda3 rootfstype=btrfs rw systemd.unit=graphical.target"
}

rEFInd does not yet support FSUUID, PARTUUID and PARTLABEL based volume/partition selection.

Re: rEFInd: how to boot an image on another partition [solved]

OK, this has been very helpful, thank you.  One question remains... why does an entry pointing to my grubx64.efi exist?

/boot/efi/EFI/refind/refind.conf

timeout 20
resolution 2560 1440

menuentry "Arch Custom" {
  icon EFI/refind/icons/os_arch.icns
  volume boot
  ostype Linux
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom.img
  options "root=/dev/sda3 rootfstype=btrfs rw quiet systemd.unit=graphical.target"
}

menuentry "Arch Custom Fallback" {
  icon EFI/refind/icons/os_arch.icns
  volume boot
  ostype Linux
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom-fallback.img
  options "root=/dev/sda3 rootfstype=btrfs rw quiet systemd.unit=graphical.target"
}

menuentry "Arch Mini" {
  icon EFI/refind/icons/os_arch.icns
  volume mini
  ostype Linux
  loader /boot/vmlinuz-linux
  initrd /boot/initramfs-linux.img
  options "root=/dev/sdb3 rootfstype=ext4 rw systemd.unit=graphical.target"
}

When rEFInd boots up, I am presented with 4 Arch icons:

[Boot EFI\arch\grubx64.efi from 98 MiB FAT volumn] [Arch Custom] [Arch Custom FB] [Mini]

Re: rEFInd: how to boot an image on another partition [solved]

Do you actually have the file \EFI\arch\grubx64.efi?  If so, then I would imagine that it is just the autoscan that is still running.  I think taht you have to explicitly disable the autoscan if you want to rely solely on the manual stanzas.

Re: rEFInd: how to boot an image on another partition [solved]

@WW - Yes, it is a backup until I am confident that rEFInd is 100 %.  This works:

timeout 5
resolution 2560 1440

showtools shell,memtest,reboot,shutdown
scanfor optical,manual
default_selection "Arch Custom"

menuentry "Arch Custom" {
  icon EFI/refind/icons/os_arch.icns
  volume boot
  ostype Linux
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom.img
  options "root=/dev/sda3 rootfstype=btrfs rw quiet systemd.unit=graphical.target"
}

menuentry "Arch Custom Fallback" {
  icon EFI/refind/icons/os_gummiboot.icns
  volume boot
  ostype Linux
  loader /vmlinuz-linux-custom
  initrd /initramfs-linux-custom-fallback.img
  options "root=/dev/sda3 rootfstype=btrfs rw quiet systemd.unit=graphical.target"
}

menuentry "Arch Mini" {
  icon EFI/refind/icons/os_arch.icns
  volume mini
  ostype Linux
  loader /boot/vmlinuz-linux
  initrd /boot/initramfs-linux.img
  options "root=/dev/sdb3 rootfstype=ext4 rw systemd.unit=graphical.target"
}

menuentry "Grub" {
  icon EFI/refind/icons/os_linux.icns
  loader /EFI/arch/grubx64.efi
}
