#. Disable Secure Boot. ZFS modules can not be loaded if Secure Boot is enabled.
#. Download a variant of `Fedora live image
<https://download.fedoraproject.org/pub/fedora/linux/releases/>`__ and boot from it.
#. Connect to the Internet.
#. Set root password or ``/root/.ssh/authorized_keys``.
#. Start SSH server::
echo PermitRootLogin yes >> /etc/ssh/sshd_config
systemctl restart sshd
#. Connect from another computer::
ssh root@192.168.1.19
#. Target disk
List available disks with::
ls /dev/disk/by-id/*
If using virtio as disk bus, use ``/dev/disk/by-path/*``.
Declare disk array::
DISK='/dev/disk/by-id/ata-FOO /dev/disk/by-id/nvme-BAR'
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
#. Check available repos::
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
