Chimera Linux

Installation

Requirements

UEFI
LVM on LUKS with unencrypted /boot

Disk partitioning

Use cfdisk to create the following partition layout.

Partition Type	Size
EFI	+600M
boot	+900M
Linux	Remaining space

Format the unencrypted partitions:

mkfs.vfat /dev/nvme0n1p1
mkfs.ext4 /dev/nvme0n1p2

Create LUKS on the remaining partition:

cryptsetup luksFormat /dev/nvme0n1p3
cryptsetup luksOpen /dev/nvme0n1p3 crypt

Create a LVM2 volume group for /dev/nvme0n1p3, which is located at /dev/mapper/crypt:

vgcreate chimera /dev/mapper/crypt

Create logical volumes in the volume group:

lvcreate --name swap -L 8G chimera
lvcreate --name root -l 100%FREE chimera

Create the filesystems for the logical volumes:

mkfs.ext4 /dev/chimera/root
mkswap /dev/chimera/swap

Create mount points for the chroot and mount the filesystems:

mkdir /media/root
mount /dev/chimera/root /media/root
mkdir /media/root/boot
mount /dev/nvme0n1p2 /media/root/boot
mkdir /media/root/boot/efi
mount /dev/nvme0n1p1 /media/root/boot/efi

Chimera-bootstrap and chroot

chimera-bootstrap /media/root

Initramfs refresh

update-initramfs -c -k all

GRUB

apk add grub-x86_64-efi
grub-install --efi-directory=/boot/efi --target=x86_64-efi

Post-installation
