rEFInd and GRUB messups of NuTyX under BtrFS

hd_scania · 01-24-2021, 11:46 PM

I have NuTyX installed on a BtrFS subvolume, and have tried auto rEFInd and GRUB-EFI, but were failed, and i’m unsure how to assign the volume argument for manual rEFInd entry as below,

Code:

menuentry "NuTyX" {
        icon     /EFI/rEFInd/icons/os_NuTyX.png
        volume   ...
        loader   /NuTyX/boot/kernel-%v
        initrd   /NuTyX/boot/initrd-%v
        options  "root=/dev/sda6 rw rootflags=subvol=NuTyX"
}

What to be entered for that argument? The main volume is on /dev/sda6 at Linux distroes, but unsure for its EFI shell volume name
And my kernels, initrd’s, and partition layouts are below,

Code:

bash-5.0$ l /boot /lib/modules $$ df

Hello again

Did you try:

Code:

menuentry "NuTyX" {
        icon     /EFI/rEFInd/icons/os_NuTyX.png
        volume   ...
        loader   /boot/kernel
        initrd   /boot/initrd
        options  "root=/dev/sda6 rw rootflags=subvol=NuTyX"
}

Beside this I won't be able to help you more as I don't know anything about this rEFInd tools.

Regards
Thierry

Yes but doesn’t help at all, so that symlinks are never accepted for rEFInd setups (Hard links? Needs manually generations, so also unlikely) ...
Even with the actual kernel and initrd file names in the manual entries, but it still doesn’t show the entry at all ...
And i’ve also tried auto mode of BtrFS subvolumes i.e. alsa_scan_dirs=NuTyX/boot in rEFInd.conf + /boot/refind_linux.conf on that NuTyX subvolume, but it always fails to load my NuTyX kernels at all.
And i also tried GRUB2-EFI, but booting into that reports UUID bugs, so that the root partition is also reported ‘‘missing’’, but not actually.

When I see your configuration you list in your signature, I'm afraid I won't be able to help you.

I feel sorry about your config.

As it seems you are not so familiar with rEFInd. I don't have any experience neither, because I feel happy with grub or syslinux.

I suggest you to start with something simpler and cleaner. By assuming you really want to stay on btrfs (which means, clearly no experience how it behave after some period of intensive usage.), here what I propose you as alternatives solutions,:
1/ Install NuTyX with the default kernel-419 without initrd. OR
2/ Install NuTyX latest kernel in bios and add an initrd OR
3/ Wait NuTyX 21.02.0 it will support Grub install on Uefi machine.

symlinks won't work on a fat partition if that is where you attempting to use them.

Mounting root filesystem using filesystem UUID involves initrd, Linux kernel cannot do it without help. However, you can use PARTUUID without initrd, kernel can read it. In any case, it eliminates one component where things can go wrong.

Indeed but symlink on a Linux partition extX, btrfs, etc filesystem pointing to a fat partition file works fine. That's what we do/mean here.
