.P
\fBifupdown-ng.\&conf\fR - Global configuration file for ifupdown-ng
.P
.SH DESCRIPTION
.P
ifupdown-ng allows to configure some parts of it'\&s behaviour via global
configuration options.\&
.P
.SH GENERAL CONFIGURATION OPTIONS
.P
\fBallow_addon_scripts\fR \fIbool\fR
.RS 4
Enable support for /etc/if-X.\&d addon scripts.\&  These are used for
compatibility with legacy setups, and may be disabled for
performance improvements in setups where only ifupdown-ng executors
are used.\&  Valid values are \fI0\fR and \fI1\fR, the default is \fI1\fR.\&
.P
.RE
\fBauto_executor_selection\fR \fIbool\fR
.RS 4
Automatically determine which executors to use.\&  At present, this
is done by inserting `use` statements for the namespace a config
option has.\&  The namespace is separated from the config option with
a dash (`-`).\&  Valid values are \fI0\fR and \fI1\fR, the default is \fI1\fR.\&
.P
.RE
\fBuse_hostname_for_dhcp\fR \fIbool\fR
.RS 4
Automatically learn the hostname property, used for DHCP
configuration by querying the system hostname using uname(2).\&
This is basically equivalent to `hostname $(hostname)` without
having to specify any configuration.\&  Valid values are \fI0\fR and
\fI1\fR, the default is \fI1\fR.\&
.P
.RE
.SH TEMPLATE RELATED OPTIONS
.P
\fBallow_any_iface_as_template\fR \fIbool\fR
.RS 4
Enable any interface to act as a template for another interface.\&
This is presently the default, but is deprecated.\&  An admin may
choose to disable this setting in order to require inheritance
from specified templates.\&  Valid values are \fI0\fR and \fI1\fR, the
default is \fI1\fR.\&
.P
.RE
\fBimplicit_template_conversion\fR \fIbool\fR
.RS 4
In some legacy configs, a template may be declared as an iface, and
ifupdown-ng automatically converts those declarations to a proper
template.\&  If this setting is disabled, inheritance will continue
to work against non-template interfaces without converting them to
a template.\&  Valid values are \fI0\fR and \fI1\fR, the default is \fI1\fR.\&
.P
.RE
.SH COMPATIBILITY RELATED OPTIONS
.P
\fBcompat_create_interfaces\fR \fIbool\fR
.RS 4
Denotes where or not to create interfaces when compat_* settings are
active and it would be necessary to create an interface to be fully
compliant.\&  This could happen when inheriting bridge VLAN settings to
an interface within a bridges bridge-ports setting but no interface
stanza is found.\&  Valid values are \fI0\fR and \fI1\fR, the default is \fI1\fR.\&
.P
.RE
compat_ifupdown2_bridge_ports_inherit_vlans \fIbool\fR
.RS 4
In ifupdown2 <bridge-vids> as well as the <bridge-pvid> set on a
bridge interface will be inherited by all member ports if not set
explicitly.\&  When set to 1 ifupdown-ng behaves the same way and will
internally copy both options from the bridge member ports if they
are not set on the member port.\&  Valid values are \fI0\fR and \fI1\fR, the
default is \fI1\fR.\&
