+    <para><filename>systemd-makefs@.service</filename>,
+    <filename>systemd-mkswap@.service</filename>, and
+    <filename>systemd-growfs@.service</filename> are used to implement the
+    <option>x-systemd.makefs</option> and <option>x-systemd.growfs</option> options
+    in <citerefentry project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+    see <citerefentry><refentrytitle>systemd.mount</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+    They are instantiated for each device for which the file system or swap structure
+    needs to be initialized, and for each mount point where the file system needs to
+    be grown.</para>
+
+    <para>These services are started at boot, either right before or right after the
+    mount point or swap device are used.</para>
+
+    <para><filename>systemd-makefs</filename> knows very little about specific file
+    systems and swap devices, and after checking that the block device does not already
+    contain a file system or other content, it will execute binaries specific to
+    each filesystem type (<filename>/sbin/mkfs.<replaceable>type</replaceable></filename>
+    or <filename>/sbin/mkswap</filename>).</para>
+
+    <para><filename>systemd-growfs</filename> knows very little about specific file
+    systems and swap devices, and will instruct the kernel to grow the mounted
+    filesystem to full size of the underlying block device. Nevertheless, it needs
+    to know the
+    <citerefentry project='man-pages'><refentrytitle>ioctl</refentrytitle><manvolnum>2</manvolnum></citerefentry>
+    number specific to each file system, so only certain types are supported.
+    Currently:
+    <citerefentry project='man-pages'><refentrytitle>ext4</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+    <citerefentry project='url'><refentrytitle url='https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs(5)'>btrfs</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+    <citerefentry project='man-pages'><refentrytitle>xfs</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+    <!-- yes, that's what the man page is called. -->
+    and dm-crypt partitions (see
+    <citerefentry project='die-net'><refentrytitle>cryptsetup</refentrytitle><manvolnum>8</manvolnum></citerefentry>).
+    </para>
+
+    <para>If the creation of a file system or swap device fails, the mount point or
+    swap is failed too. If the growing of a file system fails, a warning is emitted.
