- <para><filename>systemd-gpt-auto-generator</filename>
- is a unit generator that automatically discovers root,
- <filename>/home</filename>, <filename>/srv</filename>
- and swap partitions and creates mount and swap units
- for them, based on the the partition type GUIDs of
- GUID partition tables (GPT). It implements the <ulink
- url="http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/">Discoverable
- Partitions Specification</ulink>. Note that this
- generator has no effect 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 points are non-empty.</para>
-
- <para>This generator will only look for root
- partitions on the same physical disk the EFI System
- Partition (ESP) is located on. It will only look for
- the other partitions on the same physical disk the
- root file system is located on. These partitions will
- not be search on systems where the root file system is
- distributed on multiple disks, for example via btrfs
- RAID.</para>
-
- <para><filename>systemd-gpt-auto-generator</filename>
- 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 the partitions based on
- their partition type GUID. The following partition
