   For single disk installation, use::

    DISK='/dev/disk/by-id/disk1'

#. Set partition size:

   Set swap size. It's `recommended <https://chrisdown.name/2018/01/02/in-defence-of-swap.html>`__
   to setup a swap partition. If you intend to use hibernation,
   the minimum should be no less than RAM size. Skip if swap is not needed::

    INST_PARTSIZE_SWAP=8

   Root pool size, use all remaining disk space if not set::

    INST_PARTSIZE_RPOOL=

#. Temporarily set SELinux to permissive in live environment::

    setenforce 0

   SELinux will be enabled on the installed system.

#. Add ZFS repo::

    dnf install -y https://zfsonlinux.org/fedora/zfs-release-fedora-2-1.noarch.rpm

     dnf repolist --all

#. Install ZFS packages::

    rpm -e --nodeps zfs-fuse
    dnf install -y https://dl.fedoraproject.org/pub/fedora/linux/releases/$(source /etc/os-release; echo $VERSION_ID)/Everything/x86_64/os/Packages/k/kernel-devel-$(uname -r).rpm
    dnf install -y zfs

#. Load kernel modules::

    modprobe zfs

#. Install partition tool::

    dnf install -y gdisk dosfstools
