The status string is modeled after our --version output: +enabled -disabled equals=more-info
For example:
Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=allow-downgrade/supported
We would print the whole string as a single super-long line. Let's nicely
break the text into lines that fit on the screen.

It makes sense to ignore all the common fields that are expected and
that we can safely ignore. Note that it is fine to ignore URL as we will
already warn about the type= being wrong in that case.
Closes: #17276
This helper alone doesn't make too much sense, but it's preparatory work
for #17274, and I guess it can't hurt to land it early, it does make the
ratelimit code a tiny bit prettier after all.
This is just some refactoring: shifting around of code, not change in
codeflow.
This splits up the way too huge systemctl.c in multiple more easily
digestable files. It roughly follows the rule that each family of verbs
gets its own .c/.h file pair, and so do all the compat executable names
we support. Plus three extra files for sysv compat (which existed before
already, but I renamed slightly, to get the systemctl- prefix lik
everything else), a -util file with generic stuff everything uses, and a
-logind file with everything that talks directly to logind instead of
PID1.
systemctl is still a bit too complex for my taste, but I think this way
itc omes in a more digestable bits at least.
No change of behaviour, just reshuffling of some code.
It's an auxiliary function to the UnitInfo structures, and very generic.
Let's hence move it over to the other code operating with UnitInfo, even
if it's not used by code outside of systemctl (yet).
We have an option to set the fallback list, so we don't know what the contents
are. It may in fact be empty. Let's add some examples to make it easy for a user
stranded without any DNS to fill in something that would work. As a bonus, this
also gives names to the entries we provide by default.
(I added google and cloudflare because that's what we have currently, and quad9
because it seems to be a good privacy-concious and fast choice and was requested
in #12499. As a minimum, things we should include should be well-known global
services with a documented privacy policy and both IPv4 and IPv6 support and
decent response times.)
Also, document this functionality more prominently, including with a
reference from sd_event_exit().
This is mostly to make things complete, as previously we supported NULL
callbacks only in _add_time() and _add_signal(). However, I think this
makes snese for IO event sources too (think: when some fd such as a pipe
end sees SIGHUP or so, exit), as well as defer or post event sources (i.e. exit
once we got nothing else to do). This also adds support for inotify
event sources, simply to complete things (I can't see the immediate use,
but maybe someone else comes up with it).
The only event source type that doesn't allow callback=NULL now are exit
callbacks, but for them they make little sense, as the event loop is
exiting then anyway.
