If the ceck for the ACPI TPM2 table did not work we currently check if
the EFI TPM table exists to check if the firmware supports TPM2.
Specifically we check if
/sys/kernel/security/tpm0/binary_bios_measurements exists. But that's
not enough, since that also exists on TPM1.2 systems. Hence, let's also
check /sys/class/tpm/tpm0/tpm_version_major which should exist under
similar conditions and tells us the kernel's idea of the TPM version in
use.
I originally intended to read the signature of the
/sys/kernel/security/tpm0/binary_bios_measurements contents for this,
but this is not ideal since that file has tight access mode, and our TPM
availability check would thus not work anymore if invoked unpriv.

dbus-broker and dbus-daemon have not been made interchangable on
OpenSUSE so we currently end up with dbus-broker used for the system
bus and dbus-daemon for the session bus. Let's stick to dbus-daemon
on OpenSUSE until they switch to dbus-broker.
Otherwise we'll close the device disarming it as side-effect of
watchdog_free_device(), which is not intended. Hence, let's close the fd
first explicitly leaving it armed.
Fixes: #33075
When we open a watchdog fresh we have never pinged it, hence reset the
ping timestamp explicitly, so that it is not only reset the first time
we open the device, but all times.
The virtio-scsi driver is available in the KVM/cloud kernel
packages provided by distributions whereas the megasas2 driver is
not. Let's switch to virtio-scsi so we can switch back to the KVM/cloud
kernel packages.
Mounting multiple btrfs filesystems with the same fsid only works
properly from kernel 6.7 onwards. Let's switch to ext4 for now which
does support this.
libbpf returns error codes from the kernel unmodified, and we don't understand
them so non-fatal ones are handled as hard errors.
Add a translation helper, and start by translating 524 to EOPNOTSUPP, which is
returned when nsresourced tries to use LSM BPF hooks that are not
implemented on a given arch (in this case, arm64 is misssing trampolines).

Mention in the warning message for a failed open on a to be removed file
why systemd-tmpfiles tried to open it.
Also open the file with the O_NOCTTY flag, since it should never become
the controlling terminal.
PID1 may invoke a helper process, e.g. sd-close, during the test.
So, processes other than networkd and PID1 may be shown.

Closes#33055.
if machined exits while a machine is still running, we'll issue the
UnrefUnit() call on the unit. This quite likely will fail if during
shutdown the bus connection is already down. But that's no reason to
warn at all, since the ref count will implicitly be dropped if our side
disappears from the bus. Hence, downgrade to LOG_DEBUG in case of
connection problems.
