systemd Developer Lennart Poettering lennart@poettering.net systemd-gpt-auto-generator 8 systemd-gpt-auto-generator Generator for automatically discovering and mounting /home and /srv, as well as discovering and enabling swap partitions, based on GPT partition type GUIDs. /usr/lib/systemd/system-generators/systemd-gpt-auto-generator systemd-gpt-auto-generator is a unit generator that automatically discovers /home, /srv 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 fstab5), or where the mount points are non-empty. 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. systemd-gpt-auto-generator is useful for centralizing file system configuration in the partition table and making manual configuration in /etc/fstab or suchlike unnecessary. This generator looks for the partitions based on their partition type GUID. The following partition type GUIDs are identified: Partition Type GUID Location Explanation 0657fd6d-a4ab-43c4-84e50933c84b4f4f Swap All swap partitions are enabled. 933ac7e1-2eb4-4f13-b8440e14e2aef915 /home The first home partition on the disk is mounted to /home. 3b8f8425-20e0-4f3b-907f1a25a76f98e8 /srv The first server data partition on the disk is mounted to /srv. The /home and /srv partitions may be encrypted in LUKS format. In this case a device mapper device is set up under the names /dev/mapper/home and /dev/mapper/srv. Note that this might create conflicts if the same partition is listed in /etc/crypttab with a different device mapper device name. Also note that systemd-efi-boot-generator8 will mount the EFI System Partition to /boot is not otherwise mounted. systemd-gpt-auto-generator implements the generator specification. systemd1, systemd.mount5, systemd.swap5, systemd-fstab-generator8, systemd-efi-boot-generator8, systemd-cryptsetup@.service8, cryptsetup8, fstab5
