- <title>Description</title>
-
- <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
- 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 project='man-pages'><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 searched 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 type GUIDs are
- identified:</para>
