Maximilian Wilhelm 480fc5eecb compat: Only create interface when configured to do so. 
Add config option <compat_create_interfaces>:

  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.

ifupdown-ng

ifupdown-ng is a network device manager that is largely compatible with Debian ifupdown, BusyBox ifupdown and Cumulus Networks' ifupdown2.

For more information read the admin guide.

Dependency Resolution

Dependency resolution example

ifupdown-ng uses a dependency resolver to determine interface bring-up order in a deterministic way.

This is accomplished through a combination of manual hinting using the requires keyword and dependency learning using native executors.

For compatibility with some legacy ifupdown executors, we also provide the requires keyword under other environment variables in some cases.

Caveats

  • ifupdown2 python plugins are not supported at this time. An executor could be written to handle them.

  • ifupdown-ng retains compatibility with /etc/network/if-X.d scripts, but will prefer using executors in /usr/libexec/ifupdown-ng where appropriate.

Building

On musl systems, simply do make and make install to build and install.

On glibc systems, you must install libbsd-dev or equivalent and additionally define LIBBSD_CFLAGS and LIBBSD_LIBS:

# instal packages
apt install build-essential libbsd0 libbsd-dev

# build ifupdown-ng
make LIBBSD_CFLAGS="$(pkg-config --cflags libbsd-overlay)" LIBBSD_LIBS="$(pkg-config --cflags --libs libbsd-overlay)"
make install

To run the tests, do make check. Running the checks requires kyua (apk add kyua, not packaged for Debian).

To build the documentation, do make docs and make install_docs. Building the documentation requires scdoc (apk add scdoc / apt install scdoc).
