1. install usb stick with arch linux
2. boot from usb
3. run `fdisk -l` to find partition with linux installation (ie /dev/sda3 Linux Filesystem)
4. mount partition: `mount /dev/sda3 /mnt`
5. arch chroot into it: `arch-chroot /mnt`
6. rebuild initramfs: `mkinitcpio -p linux` (if that doesn't work yes try `pacman -S linux` only)
7. shutdown, unplug usb, reboot

- light vm layer
- can run in nested virturalization environments if hardware supports and you can enable it in bios (ex. only bare metal EC2 instances, limits many cloud providers)
- slower startup time
- OCI compliant
- previously known as ClearContainers by Intel
