Raspberry Pi Custom Installation/Preparations

Partition the SD card

root@localhost ~ # parted -a optimal /dev/mmcblk0

Create GPT partition table, set unit, and list partitions

mklabel gpt
unit mib
print

Create new primary partition for boot and another one for LVM with the rest of the card

mkpart primary fat16 4Mib 132Mib
set 1 boot on
name 1 boot
mkpart primary 132Mib -1
set 2 lvm on
name 2 lvm
print
quit

The partitions should look like this

Number  Start    End        Size       File system  Name  Flags
 1      4.00MiB  132MiB     128MiB     fat16        boot  boot, esp
 2      132MiB   122622MiB  122490MiB               lvm   lvm

Create physical volume and volume group

root@localhost ~ # pvcreate /dev/mmcblk0p2

root@localhost ~ # vgcreate rpi /dev/mmcblk0p2

Create swap partition and raspbian root

root@localhost ~ # lvcreate -L1G -nswap /dev/rpi

root@localhost ~ # lvcreate -L10G -nraspbian /dev/rpi

Format the partitions

root@localhost ~ # mkfs.vfat -nboot /dev/mmcblk0p1

root@localhost ~ # mkswap -Lswap /dev/rpi/swap

root@localhost ~ # mkfs.ext4 -Lraspbian /dev/rpi/raspbian

Double check if all is right
