<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

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
