Let's document this for now. We should be able to lift these limitations
sooner or later, at which point we can drop this documentation again.
These two limitations are a pitfall that people should be aware of,
before going FIDO2-only.
See: #20230#19208
Those devices show up as /sys/devices/vif-N, let's use that number
to name them enXN.
Without this, all schemes fail and they keep the kernel names, which can
be racy.

To prevent situations like in #17602 from happening, let's drop
direct recursive template dependencies. These will almost certainly
lead to infinite recursion so let's drop them immediately to avoid
instantiating potentially thousands of irrelevant units.
Example of a template that would lead to infinite recursion which
is caught by this check:
notify@.service:
```
[Unit]
Wants=notify@%n.service
```
When combined with a tmpfs on /run or /var/lib, allows to create
arbitrary and ephemeral symlinks for StateDirectory or RuntimeDirectory.
This is especially useful when sharing these directories between
different services, to make the same state/runtime directory 'backend'
appear as different names to each service, so that they can be added/removed
to a sharing agreement transparently, without code changes.
An example (simplified, but real) use case:
foo.service:
StateDirectory=foo
bar.service:
StateDirectory=bar
foo.service.d/shared.conf:
StateDirectory=
StateDirectory=shared:foo
bar.service.d/shared.conf:
StateDirectory=
StateDirectory=shared:bar
foo and bar use respectively /var/lib/foo and /var/lib/bar. Then
the orchestration layer decides to stop this sharing, the drop-in
can be removed. The services won't need any update and will keep
working and being able to store state, transparently.
To keep backward compatibility, new DBUS messages are added.
This is useful since certain shares can only be mounted with additional
mount flags. For example the SMB share in modern AVM Fritz!Boxes
requires "noserverino" to be set to work from Linux.
Allow specifying CIFS services in the format //host/service/subdir/… to
allow multiple homedirs on the same share, and not in the main dir of
the share.
All other backends allow placing the data store at arbitrary places,
let's allow this too for the CIFS backend. This is particularly useful
for testing.
The setting is completely meaningless, as WithoutRA= and UseDelegatedPrefix=
in [DHCPv6] section, and DHCPv6Client= in [IPv6AcceptRA] section control
the behavior.
Previously, the prefix delegation is enabled when at least one
downstream interfaces request it. But, when the DHCPv6 client on the
upstream interface is configured, some downstream interfaces may not
exist yet, nor have .network file assigned.
Also, if a system has thousands of interfaces, then the previous logic
introduce O(n^2) search.
This makes the prefix delegation is always enabled, except when it is
explicitly disabled. Hopefully, that should not break anything, as the
DHCPv6 server should ignore the prefix delegation request if the server
do not have any prefix to delegate.
This is useful if the auto-firmware setting has been disabled. The
keys used here are based on what the majority of firmware employ in
the wild.
This also ensures there's a chance for the user to discover this in
case they were too slow during POST or simply used the wrong ones.
This is supposed to be used by package/image builders such as mkosi to
speed up building, since it allows us to suppress sync() inside a
container.
This does what Debian's eatmydata tool does, but for a container, and
via seccomp (instead of LD_PRELOAD).
When Assign= in [DHCPv6PrefixDelegation] is enabled, then the kernel
will create the prefix route for the assigned address with metric 256.
When Assign= is disabled, then the kernel will create the route with
metric 1024.
For the default value, we should choose a smaller value (higher priority)
than 1024, as the unreachable routes for delegated prefix will be
configured with 1024.
This adds support for dm integrity targets and an associated
/etc/integritytab file which is required as the dm integrity device
super block doesn't include all of the required metadata to bring up
the device correctly. See integritytab man page for details.
This option has coredumpctl look at all journals instead of only the
local ones. This allows coredumpctl to show information about remote
coredumps if the coredumps are made available in /var/lib/systemd/coredump
and the corresponding journals are made available in /var/log/journal.
This is already possible using the --directory option but --all makes it
more user friendly since users don't have to enter the journal directory
anymore as long as it's available under /var/log/journal.
