serialize: add serialize_bool_elide() helper
In many case we serialize into objects that have been zero-initialized.
To save some time and resources when there are a lot of booleans, add a
helper that serializes only when the boolean is true.
The meson options split-usr, rootlibdir and rootprefix become no-ops
that print a warning if they are set to anything other than the
default values. We can remove them in a future release.
test-execute: measure and log time elapsed while running tests
In order to get a good approximation of latencies when starting
services, timestamp before/after running the test cases and print
the difference. This allows to measure while ignoring the setup/shutdown
time for the test harness.

fstab-generator: enable fsck for block device mounts specified in systemd.mount-extra=
Like we do for root= or so.
Another possible option is adding support of fifth (sixth?) field in
systemd.mount-extra=. But that may be overkill, hence let's do that
later if someone request that.
Now, gateway for routes to DNS or NTP servers should be correctly picked,
hence it is not necessary to adjust the gateway address in
dhcp4_request_route_auto() again.
Also, similar for classless static routes, let's always honor
gateway address specified in (non-classless) static routes.
network/dhcp4: always find suitable gateway for destination address
And if not found, refuse to configure the route.
If a DHCP server provides classless static or static routes, then we
should use the gateway for accessing a node in the range specified in
the route. E.g. if a DHCP server provides the default gateway is
192.168.0.1, and classless static route for 8.0.0.0/8 with gateway
192.168.0.2, then we should access 8.8.8.8 through 192.168.0.2 rather
than 192.168.0.1, but should use 192.168.0.1 for 9.9.9.9.
network/dhcp4: introduce dhcp4_get_router() helper function
Previously, we use the first router address, and if it is null, we
ignore the address. Now, we use the first non-null address. That is, if
the first router address is null, but the second is not, then we use the
second one.
That should not cause functional change in most cases, except for the case
when a DHCP server provides such spurious reply.
This is mostly for refactoring and preparation for later commits.
In it's latest release, agetty will support reading the agetty.autologin
and login.noauth credentials, so let's make sure we import those in our
getty units so they're available to agetty to read.

Reading package lists...
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
python3-lldb-14 : Conflicts: python3-lldb-x.y
python3-lldb-15 : Conflicts: python3-lldb-x.y
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
sleep: don't init /sys/power/resume if 'resume=' option is missing and EFI is disabled
Otherwise in such case a first `systemctl hibernate` would fail but would still
initialize /sys/power/resume fooling a second `systemctl hibernate` into
believing that 'resume=' is correctly set and can be used by the resume process
to find the swap device to resume from.
Workaround for CI issue, the sd-stub we build is overwritten in the final
image as the package gets pulled there, install it in the base to
work around it for now
fstab-generator: add a flag to accept entry for "/" in initrd
When both prefix_sysroot and accept_root is true, the entry for "/" will
be accepted and converted to "/sysroot/".
Why? If the entry is read from the main system's fstab, then we already
mounted /sysroot/, hence it is not and should not re-add the .mount unit
for /sysroot/. However, if we want to specify the root mount through the
kernel command line or credential, without this change, we need to
specify the same entry in the two options. E.g.
===
systemd.mount-extra=/dev/sda1:/:auto:defaults
rd.systemd.mount-extra=/dev/sda1:/sysroot:auto:defaults
===
That's inconvenient. Of course, we can dedup that by using traditional
options, but cannot when defined in credential.
This makes the behavior consistent with the way we already do for
fstab and command line options.
In initrd, entries read from fstab.extra are mounted under /sysroot.
fstab-generator: add rd.systemd.mount-extra= and friends
Previously, mounts specified in systemd.mount-extra= are equally handled
both in initrd and the main system. So, the mounts for the main system
are also mounted in initrd.
This introduces rd.systemd.mount-extra=, which specifies mounts in initrd.
Then, mounts specified in systemd.mount-extra= are still mounted both in
initrd and the main system, but prefixed with /sysroot/ when running in
initrd.
If /usr mount is picked from the main system's fstab file (prefix_sysroot
is true, and the path is prefixed as /sysroot/usr), then previously it
was installed in the wrong target unit.
mkosi: add drop-in to make emergency.service shut down the system
When the mkosi CI fails to boot, it just sits there waiting at the emergency
console until the job times out. Add a drop-in for emergency.service in the
CI configuration so that instead it exists immediately.
Currently, if an fstab entry for /boot/ exists, we'll skip to try /efi/
instead. However, if it's already using the same device as the discovered
one, we should not duplicate the mount.
pam: lower warning about closing sd-bus after fork
There is some issue in our code that triggers this warning constantly,
but it's nothing users can solve, so downgrade to debug level until
we can figure out the original issue (which is a permission denied
error on ReleaseSession D-Bus method call).

udev: set ID_PATH properties for all pci, usb, and platform devices
Before c43ff248f94266cfc93e300a2d3d163ed805e55b, the following line in
60-drm.rules also sets ID_PATH for all pci, usb, and platform devices:
===
ACTION!="remove", SUBSYSTEM=="drm", SUBSYSTEMS=="pci|usb|platform", IMPORT{builtin}="path_id"
===
Unfortunately, some existing rules rely on the unexpected behavior.
To keep the backward compatibility, let's set ID_PATH for them.

The new meson option 'default-keymap' means that by default there's always
a keymap to configure, so vconsole-setup fails. Allow to set
-Ddefault-keymap="" to disable it and skip gracefully again.
test: check if we correctly propagate /run mounts during switch root
Since 7c764d4 we bind mount certain directories during switch root
instead of moving the mount directly, and for /run we do this without
MS_REC. This, unfortunately, leaves all mounts under /run behind
in the old root, which breaks certain use cases.
