Note, most of the commands related to partitioning will require root
priveleges. Prefix them with sudo or issue them from priviledged user shell.
Some theory and concepts behind btrfs: https://fedoramagazine.org/working-with-btrfs-general-concepts/
- Enter environment, where all needed tools are available
guix shell parted cryptsetup btrfs-progs. - List all devices with
parted -l. Find appropriate one, save to variable$DISK, for exampleDISK=/dev/sda. - Make a partition table, it’s very likely you need GPT (aka GUID Partition
Table) and not MBR:
parted $DISK
4.
guix shell parted git make #btrfs-progfs
sudo parted -l
DISK=/dev/sda
# or
# DISK=/dev/nvme0n1
sudo parted $DISK
# it will open a parted prompt
mklabel gpt
# 1GiB is a safe size for EFI partition, but you probably will be fine
# with much smaller, do your research on this topic
mkpart "EFI system partition" fat32 0% 1024MiB
set 1 esp on
mkpart primary 1024MiB 100%
