#REDIRECT [[Talk:Boot loaders]]
 
 
Hi,
 
 
 
I have already posted some information on the Forums, but since this is the way to go, I'm posting my thoughts here.
 
 
 
The Wiki's says the following about rEFInd:
 
''"Note: As of refind-efi 0.6.5, refind now automatically detects kernels in /boot. They do not have to be renamed to have a .efi extension either. Hence, the following sync scripts aren't needed if using refind."''
 
 
 
But how it is possible for rEFInd to scan the /boot directory? When booting rEFInd, only the dirs inside \EFI are readable for rEFInd. I have tested this and I confirm that rEFInd can't scan /boot until it is mounted by fstab. (the actual booting process). The sync scripts seems to be needed, to successfully boot Arch.
 
 
 
 
 
As for '''Systemd Automation''' script, I find the following line a little bit weird:
 
''cp -r /usr/{share/refind/*,lib/refind/*$arch*} $refind_dir/  && ## update bin and dirs''
 
 
 
Should it not be: cp -r {/usr/share/refind/*,/lib/refind/refind_x*$arch*.efi} $refind_dir/  && ## update bin and dirs ?
 
Only the file refind_x*ARCH*, is needed for the /lib directory.
 
 
 
 
 
Also I would like to see instructions how to add a custom boot entry (if needed/other location). They are documented inside rEFInd, but not on the Wiki.
 
menuentry "Arch Linux" {
 
    icon /EFI/refind/icons/os_arch.icns
 
    loader /EFI/arch/vmlinuz-arch.efi
 
    initrd /EFI/arch/initramfs-arch.img
 
    options "root=PARTUUID=xx rootfstype=ext4 ro add_efi_memmap systemd.unit=graphical.target"
 
}
 
 
 
menuentry "Arch Linux Fallback" {
 
    icon /EFI/refind/icons/os_arch.icns
 
    loader /EFI/arch/vmlinuz-arch.efi
 
    initrd /EFI/arch/initramfs-arch-fallback.img
 
    options "root=PARTUUID=xx rootfstype=ext4 ro add_efi_memmap systemd.unit=multi-user.target"
 
}
 
 
 
 
 
Thanks

== Issue with the Systemd Automation script ==
 
 
 
Beta990 has some reason questioning the '''Systemd Automation''' script's line:
 
  cp -r /usr/{share/refind/*,lib/refind/*$arch*} $refind_dir/  && ## update bin and dirs
 
As it is on the wiki, it just prints this when launched:
 
  /usr/lib/systemd/scripts/refind_name_patchv2: ligne31: « update-efi-dir » : identifiant non valable
 
[in English: unvalid identifier].
 
Unfortunately editing that single line as follow changes nothing:
 
  cp -r /usr/{share/refind/*,lib/refind/refind_*$arch*.efi} $refind_dir/ && ## update bin and dirs
 
 
 
Next in the wiki, there might be a typo at the end of the systemctl command (see the « ; »):
 
  Tip: Enable the systemd path unit by running :
 
  # systemctl enable refind_update.path;

== MKinitcpio update hook not working ==
 
 
 
The mkinitcpio auto-update hook does not work. I get the following output: "Synced  to /boot/efi/EFI/arch", along with some cp errors. Obviously, the parameters are not passed.
 
 
 
If i replace the script with the static cp commands from incron, i get the following output, indicating that the image is copied BEFORE the new one is written:
 
 
 
      -> Running build hook: [efistub-update]
 
    Synced new kernel and initrd to EFIStub.
 
    ==> Generating module dependencies
 
    ==> Creating gzip initcpio image: /boot/initramfs-linux.img
 
    ==> Image generation successful
 
 
 
As a result, my scripts now look as follows:
 
 
 
    /usr/lib/initcpio/install/efistub-update   
 
----
 
    #!/bin/sh
 
   
 
    build() {
 
        /usr/local/sbin/efistub-update &
 
    }
 
   
 
    help() {
 
        cat <<HELPEOF
 
    This hook simply waits for mkinitcpio to finish and copies the finished ramdisk and kernel to UEFI
 
    HELPEOF
 
    }
 
 
 
and
 
 
 
    /usr/local/sbin/efistub-update
 
----
 
    #!/bin/sh
 
   
 
    while [ [ -d "/proc/$PPID" ]]; do
 
        sleep 1
 
    done
 
   
 
    /bin/cp -f /boot/vmlinuz-linux /boot/efi/EFI/EFIStub/vmlinuz-arch.efi
 
    /bin/cp -f /boot/initramfs-linux.img /boot/efi/EFI/EFIStub/initramfs-arch.img
 
    /bin/cp -f /boot/initramfs-linux-fallback.img /boot/efi/EFI/EFIStub/initramfs-arch-fallback.img
 
   
 
    echo "Synced new kernel and initrd to EFIStub."
 
 
 
 
 
 
 
Also, the watch.sh does not get chmod +x'ed in the existing example.
