<title>Description</title>
<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
+ is a unit generator that automatically discovers
+ <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). 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 point is non-empty.</para>
