clerie's Gentoo install Guide

Konzept

  • Vollverschlüsselte Festplatte
  • (U)EFI Boot direkt in den Kernel
  • Hibernate

Partitionierung

/boot/efi 512MB mkfs.fat -F 32
/boot 1G mkfs.ext4
lvm / 25GB
swap RAM+2GB
/home 100%FREE

Krypto

cryptsetup luksFormat -c aes-xts-plain64 –hash sha256 -s 256 /dev/nvme0n1p3

LVM

cryptsetup luksOpen /dev/nvme0n1p3 lvm

pvcreate /dev/mapper/lvm

vgcreate vg0 /dev/mapper/lvm

lvcreate -L50G -n root vg0

lvcreate -L18G -n swap vg0

lvcreate -l 100%FREE -n home vg0

mkfs.ext4 /dev/mapper/vg0-root

mkswap /dev/mapper/vg0-swap swapon /dev/mapper/vg0-swap

mkfs.ext4 /dev/mapper/vg0-home
