You can configure it either using the Linux kernel's IP autoconfig
feature (which is what we document in the manual), or manually using
ifconfig, or from some startup script.

/etc/network/interfaces is only relevant in a few Linux distributions
(Debian based), and requires a corresponding set of shell scripts
which get run by the init system.

This is to be expected. You don;t have a Debian distribution running.

The probably easiest way is to use the autoconfig by passing the
parameters on the kernel command line, as documented in the manual.
