3acc318591 man/soft-reboot: order surviving services before shutdown.target
Prompted by #32895

Rather than ordering with each power operation targets,
ordering against shutdown.target which is a valid
synchronization point. This has no effect if soft-reboot
is being performed.

This feature is deprecated, but if users use it, they are likely to be

82c2214539 debug-generator: Allow specifying name of unit-dropin credential
A fixed name is too rigid, let's give users the ability to define
custom drop-in names which at the same time also allows defining
multiple dropins per unit.

We use ~ as the separator because:
- ':' is not allowed in credential names
- '=' is used to separate credential from value in mkosi's --credential
  argument.
- '-' is commonly used in filenames
- '@' already has meaning as the unit template specifier which might be
  confusing when adding dropins for template units

566491c971 docs,man: Avoid some ambiguous uses of "may not"
Like much English text, the systemd documentation uses "may not" in the
sense of both "will possibly not" and "is forbidden to".  In many cases
this is OK because the context makes it clear, but in others I felt it
was possible to read the "is forbidden to" sense by mistake: in
particular, I tripped over "the target file may not exist" in
systemd.unit(5) before realizing the correct interpretation.

Use "might not" or "may choose not to" in these cases to make it clear
which sense we mean.

5b44c81ff8 machined: add varlink interface for registering machines
This commit adds the new varlink interface io.systemd.Machine at
/run/systemd/machine/io.systemd.Machine with a single method Register

1f815bf164 machined: add GetMachineSSHInfo method
Also adds three properties:
- VsockCid: the VSOCK CID of the VM
- SshAddress: the address of the VM in a format SSH can connect to
- SshPrivateKeyPath: the path to the SSH private key to use to connect
  to the VM.

GetMachineSSHInfo is essentially a convenience method to query both the
SshAddress and SshPrivateKeyPath properties at once.

systemctl: do not fall back to StartUnit automatically for sleep operations
In the majority of cases, this is caused by
sleep_supported() returning error. Hence it's
very likely that it would fail again, so
the fallback is not really useful. Instead,
honor the --force option for these verbs.

88b51ceb56 man: Remove OSConfig project mentioning for systemd-confext
The systemd-confext use case description was mentioning an OSConfig
project which won't say much to users. Also, it's good to call out that
systemd-confext provides a reliable way to manage configuration because
in contrast to other tools it will remove all old configuration files.

78a529caa5 man: improve documentation about using resource-control options
According to the documentation in systemd.resource-control(5),
resource-control options may be used in mount, scope, service,
slice, socket and swap units.
While e.g. systemd.service(5) includes that information,
documentation for some other units does not.

The most problematic example is systemd.slice(5).
Its documentation states a slice unit may only contain [Install]
and [Unit] sections, while actually it may contain also a [Slice]
section with options from systemd.resource-control(5).
units/user/app.slice is an example of a slice unit having a [Slice]
section.

07b6924de4 networkd: Correct documentation for LinkLocalAddressing
LinkLocalAddressing accepts a boolean. This can be seen by looking at
`link_local_address_family_from_strong(cont char *s)` in
`src/network/netword-util.c#L102-108` which falls back to
`address_family_from_string`, defined two lines above (L100)

8518f4a814 cryptenroll: default to block device backing /var/ rather than /
With 1df4b21abd we started to default to
enrolling into the LUKS device backing the root fs if none was specified
(and no wipe operation is used). This changes to look for /var/ instead.

On most systems /var/ is going to be on the root fs, hence this change
is with little effect.

However, on systems where / and /var/ is separate it makes more sense to
default to /var/ because that's where the persistent and variable data
is placed (i.e.  where LUKS should be used) while / doesn't really have
to be variable, could as well be immutable, or ephemeral. Hence /var/
should be a safer default.

Or to say this differently: I think it makes sense to support systems
with /var/ being on / well. I also think it makes sense to support
systems with them being separate, and /var/ being variable and
persistent. But any other kind of system I find much less interesting to
support, and in that case people should just specify the device name.

Also, while we are at it, tighten the checks a bit, insist on a dm-crypt
+ LUKS superblock before continuing.

And finally, let's print a short message indicating the device we
operate on.
