Partition Scheme

As per the UAPI Group's Boot Specification, I have an ESP (efi system partition) and a Boot Partition. Presently, they are both of type vfat32, but this may change in the future. The ESP is of size 512MB and the Boot Partition is of size 4GB. The rest of the drive is my root partition, with luks and btrfs. I normally use the following options with luks:

cryptsetup --type luks2 --hash sha512 --cipher aes-xts-plain64 --key-size 512 --pbkdf argon2id /dev/nvme0n1p3

I have the following subvolumes for my root partition:

• rootfs at /
• home at /home
• repos at /var/db/repos
• binpkgs at /var/cache/binpkgs
• distfiles at /var/cache/distfiles
• log at /var/log
• tmp at /var/tmp
• snapshots (unmounted by default)

I also create an additional /system directory where the entire btrfs filesystem is mounted at for backups automatically.

Putting this in a table:

Partition	Gdisk Hex Code	Size	Filesystem	Description
/dev/nvme0n1p1	EF00	512 MB	Fat32	EFI System Partition
/dev/nvme0n1p2	EA00	4 GB	Fat32	XBOOTLDR Partition
/dev/nvme0n1p2	8300	Rest of Disk	LUKS + BTRFS	Root Partition
