# Create a gpt partition table similar to this:
# Disk /dev/sda: 14,9 GiB, 16013942784 bytes, 31277232 sectors
# Units: sectors of 1 * 512 = 512 bytes
# Sector size (logical/physical): 512 bytes / 512 bytes
# I/O size (minimum/optimal): 512 bytes / 512 bytes
# Disklabel type: gpt
# Disk identifier: 45AA3BC2-C3B8-B24D-A5AF-59C9F2577554

# Device       Start      End  Sectors  Size Type

# /dev/sda2  1048576 31277198 30228623 14,4G Linux filesystem

# Create boot filesystem:
# mkfs.vfat -v -F32 -n BOOT /dev/sda1
#
# Create root filesystem:
# mkfs.btrfs -m single -d single -L BTRFS /dev/sda2
#
# Install syslinux:
# mount -o noatime,fmask=0133,dmask=0022,utf8 /dev/sda1 /boot
# mkdir /boot/syslinux
# syslinux -d syslinux -i /dev/sda1
# cp /usr/share/syslinux/{libutil,menu}.c32 /boot/syslinux/
# dd bs=440 count=1 if=/usr/share/syslinux/gptmbr.bin of=/dev/sda
#
# Mount root filesystem:
# mount -o noatime,ssd,compress=lzo /dev/sda2 /mnt

# Create and mount home subvolume:
# btrfs subvolume create /mnt/home
