We can later use this to adapt our announced EDNS buffer size in order
to avoid fragmentation to make the best of large datagrams while still
avoiding he security weaknesses of it.
A "Credentials" section name in systemd.exec man page was used
both for User/Group and for actual credentials support in systemd.
Rename the first instance to "User/Group Identity"
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.
