Let's allow configuring the debug tty independently of enabling/disabling
the debug shell. This allows mkosi to configure the correct tty while
leaving enabling/disabling the debug tty to the user.
Prompted by https://github.com/systemd/systemd/pull/30085#discussion_r1401534107.
Note, like Reconfigure bus method, even reconfiguration for an interface is
triggered by Reload method, the method only wait for the link enters
configuring state (or unmanaged state if no matching .network file exists).
Users still need to invoke systemd-networkd-wait-online if it is
necessary to wait for the interface enters configured state after Reload
medhod.
As described in https://github.com/systemd/systemd/issues/31235, the preset
state for systemd-homed-activate.service was unclear. On the one hand, we have
a preset with 'enable systemd-homed.service', and systemd-homed.service has
'Also=systemd-homed-activate.service systemd-homed-firstboot.service', so
'preset systemd-homed.service' would also enable those two services, but
'preset systemd-homed-activate.service' would disable it, because the presets
don't say it is enabled. It seems that this configuration is internally
inconsistent. As described in the issue, maybe systemctl should be smarter
here, or warn about such configs. Either way, let's make our config consistent.
Follow-up for d1f6e01e47 and

This new mode copies resources provided by the client, so that they
remain available for inspect/detach even if the original images are
deleted, but symlinks the profile as that is owned by the OS, so that
updates are automatically applied.
The intro of systemd-firstboot is rewritten to make it clearer how it fits into
the big picture. Systemd does some machine-id and presets and
systemd-firstboot.service is used to interactively fill in the blanks.
Closes#22225.
The send-release option only affects to the client when STOPPING. There
is no reason to do not allow this option to be set while the client is
running.
An user might want to delay the decision of sending a RELEASE message to
a later stage where the client is already running.
The personality() syscall returns a 32-bit value where the top three
bytes are reserved for flags that emulate historical or architectural
quirks, and only the least significant byte reflects the actual
personality we're interested in (in opinionated_personality()).
Use the newly defined mask in the corresponding test as well, otherwise
the test fails on some more "exotic" architectures that set some of the
"quirk" flags:
~# uname -m
armv7l
~# build/test-seccomp
...
/* test_lock_personality */
current personality=0x0
safe_personality(PERSONALITY_INVALID)=0x800000

Previously, if address_remove() or friends called with a temporary
object, the removing flag is assigned to the temporary object, and is
not set to the remembered object. Hence, e.g.
route_is_ready_to_configure() wrongly judge a required address for a
route is (still) ready, hence networkd fails to configure the route.
Fixes#28009.
Follow-up for 0a0c2672db.
After the commit, remembered Address objects by Link are always given by
kernel. Hence, it is not necessary to set the flag, as it is always
ignored by the kernel, and the kernel set the flag on notification if it
is necessary.
