                <para><filename>systemd-gpt-auto-generator</filename>
                is a generator that automatically discovers
                <filename>/home</filename> and swap partitions and
                creates mount and swap units for them, based on the
                the partition type GUIDs of GUID partition tables
                (GPT). Note that this generator will execute no
                operation on non-GPT systems, on systems where the
                units are explicitly configured (for example, listed
                in
                <citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>)
                or where the mount point is non-empty.</para>

                <para>This generator will only look for partitions on
                the same physical disk the root file system is stored
                on. This generator has no effect on systems where the
                root file system is distributed on multiple disks, for
                example via btrfs RAID.</para>

                <para>This generator is useful for centralizing file
                system configuration in the partition table and making
                manual configuration in
                <filename>/etc/fstab</filename> or suchlike
                unnecessary.</para>

                <para>This generator looks for swap partitions using
                GPT type 0657fd6d-a4ab-43c4-84e50933c84b4f4f. It looks
                for <filename>/home</filename> partitions using GPT
                type 933ac7e1-2eb4-4f13-b8440e14e2aef915.</para>
