* systemd-repart: make it a static checker during early boot for existence and
absence of other partitions for trusted boot environments
* systemd-repart: add support for GPT_FLAG_GROWFS also on real systems, i.e.
* systemd-repart: add support for SD_GPT_FLAG_GROWFS also on real systems, i.e.
generate some unit to actually enlarge the fs after growing the partition
during boot.

- in particular an example how to do the equivalent of switching runlevels
- man: maybe sort directives in man pages, and take sections from --help and apply them to man too
- document root=gpt-auto properly
- GPT_FLAG_GROWFS is not documented at all. GPT_FLAG_* should be documented in Discoverable Partitions.
* systemctl:
- add systemctl switch to dump transaction without executing it

| _Server Data Partition_ | `3b8f8425-20e0-4f3b-907f-1a25a76f98e8` | Any native, optionally in LUKS | The first partition with this type UUID on the disk containing the root partition is automatically mounted to `/srv/`. If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/srv`. |
| _Variable Data Partition_ | `4d21b016-b534-45c2-a9fb-5c16e091fd2d` | Any native, optionally in LUKS | The first partition with this type UUID on the disk containing the root partition is automatically mounted to `/var/` — under the condition that its partition UUID matches the first 128 bits of `HMAC-SHA256(machine-id, 0x4d21b016b53445c2a9fb5c16e091fd2d)` (i.e. the SHA256 HMAC hash of the binary type UUID keyed by the machine ID as read from [`/etc/machine-id`](https://www.freedesktop.org/software/systemd/man/machine-id.html). This special requirement is made because `/var/` (unlike the other partition types listed here) is inherently private to a specific installation and cannot possibly be shared between multiple OS installations on the same disk, and thus should be bound to a specific instance of the OS, identified by its machine ID. If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/var`. |
| _Temporary Data Partition_ | `7ec6f557-3bc5-4aca-b293-16ef5df639d1` | Any native, optionally in LUKS | The first partition with this type UUID on the disk containing the root partition is automatically mounted to `/var/tmp/`. If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/tmp`. Note that the intended mount point is indeed `/var/tmp/`, not `/tmp/`. The latter is typically maintained in memory via `tmpfs` and does not require a partition on disk. In some cases it might be desirable to make `/tmp/` persistent too, in which case it is recommended to make it a symlink or bind mount to `/var/tmp/`, thus not requiring its own partition type UUID. |
| _Per-user Home Partition_ | `773f91ef-66d4-49b5-bd83-d683bf40ad16` | Any native, optionally in LUKS | A home partition of a user, managed by [`systemd-homed`](https://www.freedesktop.org/software/systemd/man/systemd-homed.html). |
| _Generic Linux Data Partition_ | `0fc63daf-8483-4772-8e79-3d69d8477de4` | Any native, optionally in LUKS | No automatic mounting takes place for other Linux data partitions. This partition type should be used for all partitions that carry Linux file systems. The installer needs to mount them explicitly via entries in `/etc/fstab`. Optionally, these partitions may be encrypted with LUKS. This partition type predates the Discoverable Partitions Specification. |
| _Root Partition (Alpha)_ | `6523f8ae-3eb1-4e2a-a05a-18b695ae656f` `SD_GPT_ROOT_ALPHA` | Any native, optionally in LUKS | On systems with matching architecture, the first partition with this type UUID on the disk containing the active EFI ESP is automatically mounted to the root directory `/`. If the partition is encrypted with LUKS or has dm-verity integrity data (see below), the device mapper file will be named `/dev/mapper/root`. |

This partition type is defined by the [UEFI Specification](http://www.uefi.org/specifications). |

| _Variable Data Partition_ | `4d21b016-b534-45c2-a9fb-5c16e091fd2d` `SD_GPT_VAR` | Any native, optionally in LUKS | The first partition with this type UUID on the disk containing the root partition is automatically mounted to `/var/` — under the condition that its partition UUID matches the first 128 bits of `HMAC-SHA256(machine-id, 0x4d21b016b53445c2a9fb5c16e091fd2d)` (i.e. the SHA256 HMAC hash of the binary type UUID keyed by the machine ID as read from [`/etc/machine-id`](https://www.freedesktop.org/software/systemd/man/machine-id.html). This special requirement is made because `/var/` (unlike the other partition types listed here) is inherently private to a specific installation and cannot possibly be shared between multiple OS installations on the same disk, and thus should be bound to a specific instance of the OS, identified by its machine ID. If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/var`. |

If the partition is encrypted with LUKS, the device mapper file will be named `/dev/mapper/tmp`. Note that the intended mount point is indeed `/var/tmp/`, not `/tmp/`. The latter is typically maintained in memory via `tmpfs` and does not require a partition on disk. In some cases it might be desirable to make `/tmp/` persistent too, in which case it is recommended to make it a symlink or bind mount to `/var/tmp/`, thus not requiring its own partition type UUID. |
| _Per-user Home Partition_ | `773f91ef-66d4-49b5-bd83-d683bf40ad16` `SD_GPT_USER_HOME` | Any native, optionally in LUKS | A home partition of a user, managed by [`systemd-homed`](https://www.freedesktop.org/software/systemd/man/systemd-homed.html). |

## Partition Flags
## Partition Attribute Flags
This specification defines three GPT partition flags that may be set for the
partition types defined above:
This specification defines three GPT partition attribute flags that may be set
for the partition types defined above:
1. For the root, `/usr/`, Verity, Verity signature, home, server data, variable

for the specific partition. If set, the partition will not be automatically

partition flag bit 63 ("*no-auto*", *SD_GPT_FLAG_NO_AUTO*) may be used to
turn off auto-discovery for the specific partition. If set, the partition
will not be automatically mounted or enabled.
2. For the root, `/usr/`, Verity, Verity signature home, server data, variable
data, temporary data and extended boot loader partitions, the partition flag
bit 60 ("*read-only*") may be used to mark a partition for read-only mounts
only. If set, the partition will be mounted read-only instead of
read-write. Note that the variable data partition and the temporary data
partition will generally not be able to serve their purpose if marked
read-only, since by their very definition they are supposed to be
mutable. (The home and server data partitions are generally assumed to be
mutable as well, but the requirement for them is not equally strong.)
Because of that, while the read-only flag is defined and supported, it's
almost never a good idea to actually use it for these partitions. Also note
that Verity and signature partitions are by their semantics always
bit 60 ("*read-only*", *SD_GPT_FLAG_READ_ONLY*) may be used to mark a

it's almost never a good idea to actually use it for these partitions. Also
note that Verity and signature partitions are by their semantics always
read-only. The flag is hence of little effect for them, and it is
recommended to set it unconditionally for the Verity and signature partition
types.
3. For the root, `/usr/`, home, server data, variable data, temporary data and
extended boot loader partitions, the partition flag bit 59
("*grow-file-system*") may be used to mark a partition for automatic growing
of the contained file system to the size of the partition when
mounted. Tools that automatically mount disk image with a GPT partition
table are suggested to implicitly grow the contained file system to the
partition size they are contained in, if they are found to be smaller. This
flag is without effect on partitions marked read-only.
("*grow-file-system*", *SD_GPT_FLAG_GROWFS*) may be used to mark a partition
for automatic growing of the contained file system to the size of the
partition when mounted. Tools that automatically mount disk image with a GPT
partition table are suggested to implicitly grow the contained file system

Note that the first two flag definitions happen to correspond nicely to the
same ones used by Microsoft Basic Data Partitions.
