+## Mkinitfs
+
+[Mkinitfs](https://gitlab.alpinelinux.org/alpine/mkinitfs) is the `initramfs` generator of [Alpine Linux](https://alpinelinux.org/). Among the usual operations to setup `zlevis`, i.e. writing the encryption key of the ZFS root pool to the TPM after the creation of the ZFS root pool, enabling the `zlevis-hook` in `mkinitfs.conf` and installing `zlevis` on the host system, we require to make an adaptation to the `initramfs-init` script of `mkinitfs`. 
+
+Particularly, in the `prepare_zfs_root()` function we need to add the option `zlevis decrypt "$_root_pool" | zfs load-key -L prompt "$_root_pool"`:
+
+
+``` shell title="/usr/share/mkinitfs/initramfs-init" hl_lines="19" linenums="385"
+# Do some tasks to make sure mounting the ZFS pool is A-OK
+prepare_zfs_root() {
+	local _root_vol=${KOPT_root#ZFS=}
+	local _root_pool=${_root_vol%%/*}
+
+	# Force import if this has been imported on a different system previously.
+	# Import normally otherwise
+	if [ "$KOPT_zfs_force" = 1 ]; then
+		zpool import -N -d /dev -f $_root_pool
+	else
+		zpool import -N -d /dev $_root_pool
+	fi
+
+
+	# Ask for encryption password
+	if [ $(zpool list -H -o feature@encryption $_root_pool) = "active" ]; then
+		local _encryption_root=$(zfs get -H -o value encryptionroot $_root_vol)
+		if [ "$_encryption_root" != "-" ]; then
+			zlevis decrypt "$_root_pool" | zfs load-key -L prompt "$_root_pool" || eval zfs load-key $_encryption_root
+		fi
+	fi
+}
+```
+
+Retaining the fallback to `eval zfs load-key` with the `||` operator.
+
+Furthermore, we need to configure the `zlevis-hook` by notifying `mkinitfs` which binaries and libraries to add into the `initramfs`:
+
+``` shell title="/etc/mkinitfs/features.d/zlevis.files"
+/usr/bin/zlevis
+/usr/bin/zlevis-decrypt
+/usr/bin/tpm2*
+/usr/bin/jose
+/usr/lib/libtss2-tcti*
+```
+
+and to notify what kernel drivers are required:
+
+``` shell title="/etc/mkinitfs/features.d/zlevis.modules"
+kernel/drivers/char/tpm*
+```
+
+## Dracut
+
+Work in progress.
