TL;DR

You should really read the proper installation documentation. While the extent of it may seem somewhat intimidating, that’s only because Chimera covers a lot of platforms and potential layouts/setups.

The actual installation should be very easy, even if it’s manual. In any case, here are a few TL;DR basic setups, in the form of a command sequence. The setups are intentionally variable and should often not be used as-is, as every computer is a little different and may have different disk names, swap sizes, and so on.

Multi-boot is not covered here.

Any UEFI, NVMe, local install, GNOME image, whole disk, unencrypted

This will install Chimera from the GNOME image with the GNOME desktop, using a whole NVMe disk, on an ordinary (usually x86_64) UEFI computer. An 8GB swap partition will be used.

The same instructions will work on any UEFI machine, but grub-x86_64-efi will need to be changed to grub-arm64-efi or whichever the user needs.

# wipefs -a /dev/nvme0n1
# sfdisk /dev/nvme0n1 <<EOF

name=esp, size=100M, type="EFI System"
name=swap, size=8G, type="Linux swap"

OpenPOWER POWER9, sda1, network install, base image, desktop, LVM on LUKS

This will install Chimera with GNOME desktop from the console image using the network and will use LUKS encryption with LVM on top, on a POWER9 computer such as the Talos 2. It is assumed that the live session is on the network. A SATA drive will be used (sda1). The 8GB swap is added in the LVM.

# wipefs -a /dev/sda
# sfdisk /dev/sda <<EOF

x86_64 legacy BIOS, sda1, root on ZFS, network install, console

This will install Chimera with pure console environment using the network, and will put root filesystem on ZFS. The /boot filesystem will be separate. No swap will be used.

# sfdisk /dev/sda <<EOF
