e1fac8a68a Move the Commands section above Options section
For executables which take a verb, we should list the verbs first, and
then options which modify those verbs second. The general layout of
the man page is from general description to specific details, usually
Overview, Commands, Options, Return Value, Examples, References.

800603524a networkd: drop DHCPv4 config on stop, keep on restart, by default
This partially reverts 95355a281c.

It seems that other parts of link_stop_clients() should be skipped
when restarting, but I don't know enough about those other clients to have
an opinion if it is better to stop&start them on restart or not.
Anyway, that can be done in later patches now that the support for restarts
is there.

Fixes #13625.

afe42aef39 dhcp4: make IPServiceType configurable
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.

047f5d63d7 cgroup: introduce support for cgroup v2 CPUSET controller
Introduce support for configuring cpus and mems for processes using
cgroup v2 CPUSET controller.  This allows users to limit which cpus
and memory NUMA nodes can be used by processes to better utilize
system resources.

The cgroup v2 interfaces to control it are cpuset.cpus and cpuset.mems
where the requested configuration is written.  However, it doesn't mean
that the requested configuration will be actually used as parent cgroup
may limit the cpus or mems as well.  In order to reflect the real
configuration cgroup v2 provides read-only files cpuset.cpus.effective
and cpuset.mems.effective which are exported to users as well.

db11487d10 manager: put bin before sbin for user instances
Traditionally, user logins had a $PATH in which /bin was before /sbin, while
root logins had a $PATH with /sbin first. This allows the tricks that
consolehelper is doing to work. But even if we ignore consolehelper, having the
path in this order might have been used by admins for other purposes, and
keeping the order in user sessions will make it easier the adoption of systemd
user sessions a bit easier.

Fixes #733.
https://bugzilla.redhat.com/show_bug.cgi?id=1744059

OOM handling in manager_default_environment wasn't really correct.
Now the (theorertical) malloc failure in strv_new() is handled.

Please note that this has no effect on:
- systems with merged /bin-/sbin (e.g. arch)

- when there are no binaries that differ between the two locations.

  E.g. on my F30 laptop there is exactly one program that is affected:
  /usr/bin/setup -> consolehelper.

  There is less and less stuff that relies on consolehelper, but there's still
  some.

So for "clean" systems this makes no difference, but helps with legacy setups.

0e4a4f56be journalctl: Make journalctl --user-unit= match on _SYSTEMD_USER_SLICE
journalctl --unit= already did this, and allows you to tail all the logs
for a certain slice easily. It seemed only natural to make --user-unit
behave in a similar way.

The _SYSTEMD_USER_SLICE field was not documented as being added by
journald, so I have added that to the documentation too.

Furthermore, I have documented the existing behaviour of --unit= and the
new behaviour of --user-unit=

The behaviour was actually not documented before, so I am also OK with
removing the match for the --unit= command instead.  The user would then
have to manually provide _SYSTEMD_SLICE= filter to journalctl in both
cases. Both options work for me.
