When an interface is being reconfigured with different bridge vlan
settings, this makes old vlan IDs on the interface removed.
This also makes the PVID= setting support negative boolean value, e.g. "no",
in which case, the currently assigned PVID (typically, assigned by the
kernel when an interface is joined to a bridge) is dropped.
This feature is requested by #15291.
Note, if a .network file has no settings about bridge vlan, networkd
keeps the currently assigned vlan IDs. That's intended, to make not
break existing setups.
When a .network file has only PVID=no line in [BridgeVLAN] section, then
all assigned vlan IDs are removed.
Fixes#29975.
Closes#15291.
- AF_BRIDGE is not invalid. But we are not interested in it, currently.
- Also, we are not interested in non-static neighbors, at least
currently,
- As already commented, the kernel sends message about neighbors after
sending RTM_DELLINK. In that case, the corresponding Link object is
already removed, and there is nothing we need to do in that case.
Loading the SELinux DB on every invocation can be slow and
takes 2ms-10ms, so do not initialize it unconditionally, but
wait for the first use. On a mkosi Fedora rawhide image, this
cuts the number of loads in half.
In systemctl-show we only show current swap if ever swapped or non-zero. This
reduces the noise on swapless systems, that would otherwise always show a swap
value that never has the chance to become non-zero. It further reduces the
noise for services that never swapped.
Firmware may not have loaded a devicetree, for example if the device
shipped with windows and exclusively supports ACPI.
We should always load the specified devicetree regardless of firmware
state to enable booting on platforms where Linux only supports DT.
Note: in _cleanup, the orig. config is NULL in this case, and passing
NULL to InstallConfigurationTable is permitted by the EFI spec.

At first I thought when using --copy-from= that it was copying in my
whole disk into a partition instead of just a partition into a
partition.
Let's make the log message clearer and say that we copy starting from an
offset.
This combines exec_context_determine_tty_size() and
terminal_set_size_fd() since we always use one after the other.
Also make exec_context_determine_tty_size() return void, since it cannot
fail.
Previously, Link.dhcp6_configured flag was unconditionally used even if
the route is configured based on the DHCPv4 protocol.
Follow-up for a27588d4e7 and
e49bad0179.
Otherwise we might still use the more restrictive limit when we get to
STDOUT_STREAM_RUNNING, causing unexpected line breaks in the journal
messages.
