Enabling "saving last boot choice" in garuda boot options doesn't work for me (it won't save the last boot option), and after each boot i get this grub error: "Sparse file is not allowed"
The reason is the grub.env which is on a filesystem not writable by grub and Garuda grub config defaults to writing the selected entry to grub.env. To work around it edit your
/etc/default/grub and change from
rebuild grub config
sudo grub-mkconfig -o /boot/grub/grub.cfg
Depending on your requirements you may need to change other settings as well.
