The sysroot mount is already taken care of by the add_sysroot_mount function. With this condition left in, we can get something like this:
initrd-root-fs.target.requires
`-- usr.mount -> /run/systemd/generator/usr.mount
in the main system (i.e., not in the initramfs). In the initramfs, the previous condition already kicks in.

If a unit was pulled by a Wants= dependency but its unit file was not
present then we logged this as an error.
However Wants= might be used to configure a soft/optional dependency
on another unit, ie. start an optional service only if it's installed
otherwise simply skip it. In this case emitting an error doesn't look
appropriate.
But it's still an error if the optional dependency exists but its
activation fails for any reasons.

When a unit was started with "systemctl --user" and it failed, error
messages is printed as "systemctl status". But it should be "systemctl
--user status".
gcc is confused by the common idiom of
return errno ? -errno : -ESOMETHING
and thinks a positive value may be returned. Replace this condition
with errno > 0 to help gcc and avoid many spurious warnings. I filed
a gcc rfe a long time ago, but it hard to say if it will ever be
implemented [1].
Both conventions were used in the codebase, this change makes things
more consistent. This is a follow up to bcb161b023.

In contrast to ascii_strcasecmp_nn() it takes two character buffers with their individual length. It will then compare
the buffers up the smaller size of the two buffers, and finally the length themselves.
Properly handle RRs that begin with an asterisk label. These are the unexpanded forms of wildcard domains and appear in
NSEC RRs for example. We need to make sure we handle the signatures of these RRs properly, since they mostly are
considered normal RRs, except that the RRSIG labels counter is one off for them, as the asterisk label is always
excluded of the signature.
Allow for overriding all other machine-ids which may be present on
the system using a kernel command line systemd.machine_id or
--machine-id= option.
This is especially useful for network booted systems where the
machine-id needs to be static, or for containers where a specific
machine-id is wanted.
Set SD_EVENT_PROFILE_DELAYS to activate accounting and periodic logging
of the distribution of delays between sd_event_run() calls.
Time spent in dispatching as well as time spent outside of
sd_event_run() is measured and accounted for. Every 5 seconds a
logarithmic histogram loop iteration delays since 5 seconds previous is
logged.
This is useful in identifying the frequency and magnitude of latencies
affecting the event loop, which should be kept to a minimum.
