This was changed in commit 482efedc08,
which was released in v243, to only enable and never disable IPv6.

Our own config generates logs like this:
systemd-sysctl[1280]: Not setting net/ipv4/conf/all/rp_filter (explicit setting exists).
systemd-sysctl[1280]: Not setting net/ipv4/conf/default/rp_filter (explicit setting exists).
systemd-sysctl[1280]: Not setting net/ipv4/conf/all/accept_source_route (explicit setting exists).
systemd-sysctl[1280]: Not setting net/ipv4/conf/default/accept_source_route (explicit setting exists).
systemd-sysctl[1280]: Not setting net/ipv4/conf/all/promote_secondaries (explicit setting exists).
systemd-sysctl[1280]: Not setting net/ipv4/conf/default/promote_secondaries (explicit setting exists).
There is no error and nothing really to see.
Rolling releases, like ArchLinux, do not set VERSION_ID in
their os-release files, so allow matching simply on ID if the host
does not provide anything.
I don't think it makes sense to complete --legend=yes. It is the default, and
it would be only used very rarely (and then it is easy enough to just remove
the '=no' part from the suggested string).
--no-legend is replaced by --legend=no.
--quiet now implies --legend=no, but --legend=yes may be used to override that.
--quiet controls hints and warnings and such, and --legend controls just the
legends. I think it makes sense to allow both to controlled independently, in
particular --quiet --legend makes sense when using systemctl in a script to
provide some user-visible output.
Fixes#18560.
We were passing a reference to 'int arg_seal' to config_parse_bool(),
which expects a 'bool *'. Luckily, this would work, because 'bool'
is smaller than 'int', so config_parse_bool() would set the least-significant
byte of arg_seal. At least I think so. But let's use consistent types ;)
Also, modernize style a bit and don't use integers in boolean context.
This nicely covers the case when optarg is optional. The same parser can be
used when the option string passed to getopt_long() requires a parameter and
when it doesn't.
The error messages are made consistent.
Also fixes a log error c&p in --crash-reboot message.
We almost never use the named enum type, in almost all cases we use
"int" instead, since we overload it with negative errnos. To simplify
things, let's use "int" really everywhere.
Moreover, let's rename the fields for this enum to "type_or_errno", to
make the overloading clear. And let's ad some assertions that things are
in the right range.
If the server doesn't copy the DO bit from request to response, this is
a very early and easy indication that it doesn#t support DNSSEC
properly. Hence, let's immediately downgrade to non-DNSSEC mode if we
see this – if permissive mode is on and this is allowed.
When a subshell is used ('make' or 'make all') the LOOPDEV environment
variable, which is used to store the opened loop device, is lost.
So the cleanup on trap/exit doesn't do anything, and the loop
device used to mount the test image is left around.
Avoid using a subshell to fix the issue.
This is an updated version of #8608 with more restrictive logic. To
quite the original bug:
Some captive portals, lie and do not respond with the captive portal
IP address, if the query is with EDNS0 enabled and D0 bit set to
zero. Thus retry "secure" domain name look ups with less secure
methods, upon NXDOMAIN.

Yes, this fix sucks hard, but I guess this is what we need to do to make
sure resolved works IRL.
Heavily based on the original patch from Dimitri John Ledkov, and I
copied the commentary verbatim.
