# ifupdown-ng
|
|
|
|
ifupdown-ng is a network device manager that is largely compatible with Debian
|
|
ifupdown, BusyBox ifupdown and Cumulus Networks' ifupdown2.
|
|
|
|
## Dependency Resolution
|
|
|
|
|
|
|
|
ifupdown-ng uses a dependency resolver to determine interface bring-up order
|
|
in a deterministic way. To use this feature, you must declare relationships
|
|
between interfaces with the `requires` keyword. This keeps the implementation
|
|
efficient. For convenience, the `requires` keyword is exported to executors
|
|
as the `IF_REQUIRES` environment variable.
|
|
|
|
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 additionally define LIBBSD_CFLAGS and LIBBSD_LIBS:
|
|
|
|
export LIBBSD_CFLAGS=$(pkg-config --cflags libbsd-overlay)
|
|
export LIBBSD_LIBS=$(pkg-config --libs libbsd-overlay)
|
|
make
|
|
make install
|
|
|
|
To run the tests, do `make check`.
|
|
|
|
To build the documentation, do `make docs` and `make install_docs`. Building
|
|
the documentation requires scdoc (`apk add scdoc`).
