We'd print everything jumbled together:

Previously, "systemctl edit" exclusively used the service manager's
per-unit FragmentPath property to figure out which file to edit, when
operating on a non-template unit. If for some reason loading the unit
file failed entirely though (LoadState=error), then FragmentPath would
be empty, and thus the unit not editable.
Let's fix this, by falling back to client-side unit file searching in
this case.
(Also, various other clean-ups to make the relevant functions follow our
coding style)
Fixes: #9561
add new "systemd-run-generator" for running arbitrary commands from the kernel command line as system services using the "systemd.run=" kernel command line switch
Otherwise, some tests may disturb others, e.g.,
NetworkdNetWorkTests.test_routing_policy_rule_port_range and
NetworkdNetWorkTests.test_routing_policy_rule.
This switches the RFC3704 Reverse Path filtering from Strict mode to Loose
mode. The Strict mode breaks some pretty common and reasonable use cases,
such as keeping connections via one default route alive after another one
appears (e.g. plugging an Ethernet cable when connected via Wi-Fi).
The strict filter also makes it impossible for NetworkManager to do
connectivity check on a newly arriving default route (it starts with a
higher metric and is bumped lower if there's connectivity).
Kernel's default is 0 (no filter), but a Loose filter is good enough. The
few use cases where a Strict mode could make sense can easily override
this.
The distributions that don't care about the client use cases and prefer a
strict filter could just ship a custom configuration in
/usr/lib/sysctl.d/ to override this.
DNS_PACKET_PAYLOAD_SIZE_MAX is limiting the size of the stub replies to
512 with EDNS off or 4096 with EDNS on, without checking the protocol
used. This makes TCP replies for clients without EDNS support to be
limited to 512, making the truncate flag useless if the query result is
bigger than 512 bytes.
This commit increases the size of TCP replies to DNS_PACKET_SIZE_MAX
Fixes: #10816
Previously, we'd link the unit file into /etc in this case, but that
should only be done if the unit file is not in the search path anyway,
and this is already done implicitly anyway for all enabled unit files,
hence no reason to duplicate this here.
Fixes: #10253
Quite often when we generate objects some fields should only be
generated in some conditions. Let's add high-level support for that.
Matching the existing JSON_BUILD_PAIR() this adds
JSON_BUILD_PAIR_CONDITIONAL() which is very similar, but takes an
additional parameter: a boolean condition. If "true" this acts like
JSON_BUILD_PAIR(), but if false then the whole pair is suppressed.
This sounds simply, but requires a tiny bit of complexity: when complex
sub-variants are used in fields, then we also need to suppress them.
