NAME

       ifupdown-ng.conf - Global configuration file for ifupdown-ng

DESCRIPTION

       ifupdown-ng allows to configure some parts of it's behaviour via global configuration
       options.

GENERAL CONFIGURATION OPTIONS

       allow_addon_scripts bool
           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 0 and 1, the default is 1.

       auto_executor_selection bool
           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 0 and 1, the default is 1.

       use_hostname_for_dhcp bool
           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 0 and 1, the default is
           1.

TEMPLATE RELATED OPTIONS

       allow_any_iface_as_template bool
           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 0 and 1, the default
           is 1.

       implicit_template_conversion bool
           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 0 and 1, the default is 1.

COMPATIBILITY RELATED OPTIONS

       compat_create_interfaces bool
           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 0 and 1, the default is 1.

       compat_ifupdown2_bridge_ports_inherit_vlans bool
           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 0 and 1, the default
           is 1.
