+# Some simple tests of the initramfs network configuration.
+
+# The basic idea is to make an ext2 root image that only ships a /sbin/init to
+# just gather some data and shutdown again and boot it in qemu system
+# emulation (not KVM, so it can be run in the autopkgtest architecture without
+# hoping nested kvm works). Currently it only sets up qemu user networking
+# which limits our ability to be clever. In the long run we should set up a
+# tun and a bridge and specify the mac address of the NICs in the emulated
+# system and run dnsmasq on it so we test ipv6 and can control which ips which
+# nics get and so on -- but this is still better than nothing.
+
+# TODO: Add a test case for classless static routes. This needs support in
+# Qemu first. Following patch should be refreshed:
