What is the purpose of these overlapping partitions?

I want to install Parabola on one of my machines, so I downloaded the .iso, checked the signature and hash, and then flashed the image to a USB thumb drive like so: dd if=parabola-dual-openrc-cli-2020.01.18-netinstall.iso of=/dev/sde oflag=direct bs=1M status=progress This seems to work as intended, as I can now boot from this drive, but I discovered […]

How can I install GRUB2 on its own BTRFS subvolume?

I created a subvolume called grub, mounted it as /boot/grub, used grub-mkconfig -o /boot/grub/grub.cfg to create a config file and installed it using grub-install –efi-directory=/root/efi –target=x86_64-efi –recheck /dev/nvme0n1. After rebooting, it just shows the rescue shell and I have to enter configfile (hd0,gpt3)/grub/grub.cfg to get the menu. How can I fix this? fstab: # /dev/nvme0n1p3 […]
