grub-mkconfig mount /tmp/grub-btrfs special device does not exist

Hi Arch-ers,

Continuing with my first Arch install with btrfs and grub-mkconfig -o /boot/grub/grub.cfg results in the following:

nano /etc/mkinitcpio.conf
> add ' btrfs ' to  MODULES()  ->  MODULES=(btrfs)
mkinitcpio -p linux
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

any idea what I am doing wrong?

Would appreciate your professional guidance.

Thanks

did you figure this out - I have the same issue.

       dmesg(1) may have more information after failed mount system call.

Hi there,
I abandoned that install and tried another way if I remember correctly.
Sorry I can't help you.
