Could not find the root partition

[UltraBlackLinux]

Hey there, this time I actually have no idea, what I could do. Whenever I run refind-btrfs it errros ERROR: Could not find the root partition!

menuentry "Arch Linux" {
    icon     /EFI/refind/themes/refind-theme-regular/icons/512-192/os_arch.png
    volume   "4f58220f-2b24-374a-96c3-7d9c60290781"
    loader   /@/boot/vmlinuz-%v-zen
    initrd   /@/boot/initramfs-%v.img
    options  "root=PARTUUID=4f58220f-2b24-374a-96c3-7d9c60290781 rw add_efi_memmap rootflags=subvol=@ initrd=\boot\amd-ucode.img rd.udev.log_priority=3 vt.global_cursor_default=0 systemd.unified_cgroup_hierarchy=1 loglevel=3 sysrq_always_enabled=1 iommu=soft"
    submenuentry "Boot using fallback initramfs" {
        initrd /@/boot/initramfs-linux-fallback.img
    }
    submenuentry "Boot to terminal" {
        add_options "systemd.unit=multi-user.target"
    }
}

sda1 is my root partition

{
               "name": "sda1",
               "uuid": "6e6211b4-cfb4-44c0-8970-5e4a826e0c5e",
               "partuuid": "4f58220f-2b24-374a-96c3-7d9c60290781"
}

I already tried replacing both uuids with the partuuid, none of which worked, even though both variables are only supposed to have a partuuid.

Adding insult to injury, I have no idea, when to prepend what to the paths of the initframs and vmlinuzs. Just by trying out various configurations I got to this point:

Searching for snapshots of the '@' subvolume in the '/.snapshots/4840/snapshot/.snapshots' directory.
Found subvolume '@' mounted as the root partition.
Found 29 snapshots of the '@' subvolume.
Searching for the 'refind.conf' file on '/dev/sda2'.
Analyzing the 'refind.conf' file.
Found 1 boot stanza matched with the root partition.
...
Initializing the static partition table for subvolume '@/.snapshots/4810/snapshot' from its fstab file.
Found 29 snapshots for addition.
...
WARNING: Could not find the root partition in the '@/.snapshots/4810/snapshot' subvolume's static partition table!
WARNING: None of the snapshots for addition are usable!
WARNING: None of the prepared snapshots are matched with the 'Arch Linux' boot stanza!
ERROR: None of the matched boot stanzas can be combined with any of the prepared snapshots!

Tweaking some more I got the error I mentioned in the beginning. What is the correct configuration? Thanks!

Paste the contents of your main fstab file (the one found in the @ subvolume). Also, check the contents of the snapshotted fstab file (found in, for example, @/.snapshots/4810/snapshot/etc) and paste its content if they aren't identical to the main fstab file's contents.

diff'ed both files and they are the same.

I also already tried prepending the @ of the root partition with a \ in the refind config, but that did nothing at all

Try removing the "#Modified_by_garuda-hotfixes(1)" comments in both the main fstab file and also the snapshotted one. If it is a read-only snapshot you can either convert it to a writable one ("btrfs property set -ts /path/to/snapshot ro false") or create another snapshot of @ AFTER you've removed those comments.

I handle comments (ignore them completely, that is) only if they're occupying the whole line of text by themselves, not if they're combined with actual partition definitions.

That now returned the above. I thought %v was a valid placeholder for kernel versions?

Edit: Just tried booting that, and it's apprently not valid

Placeholders are not handled by this tool because it's primarily intended for Arch Linux where there's no such concept (AFAIK) - there's only "vmlinuz-linux" (vanilla), "vmlinuz-linux-lts", "vmlinuz-linux-zen", ... but there is no (for example) "vmlinuz-linux-5.10-lts".

Hm, sorry - it seems that you are running (in fact) Arch... I guess I'll have to somehow handle those variables as well as inline fstab comments.

I'm just gonna remove them. Still need to debug why it's not booting xD I think there is something wrong with my btrfs paths

Edit: Oh hey it's working Edit 2: refind-btrfs is too

Thank you for your help!

(Also what about the comments thing?)

That one is definitely a bug so open another issue, please.
