loadkeys for your keyboard
Select device with fdisk -l ; VM devices starts with V here, as in /dev/vda1 et
Partitionning
fdisk /dev/vda
- Use g to create a GPT partition table on /dev/vda1
- Use n to create a first EFI partition
- Use +300M to make it 300M in size
- Use t to change its type to 1 to make it an EFI partition
- Use n to create a second partition for the rest of the disk
- Use p to check for values and mistakes
- Use w to write the modifications and exit the interactive fdisk prompt
Formatting
- mkfs.fat -F 32 /dev/vda1
- mkfs.btrfs /dev/vda2
Start mounting an dplaying with BTRFS (04:50)
- mount /dev/vda2 /mnt
- create subvolumes with
btrfs subvolume create /mnt/@ btrfs subvolume create /mnt/@home btrfs subvolume create /mnt/@snapshots
(Reminder : subvolumes don't create snapshots of nested subvolumes ; here @ won't contain @home or @snapshots data)
