4 | # networkd integration test | |
5 | # This uses temporary configuration in /run and temporary veth devices, and | |
6 | # does not write anything on disk or change any system configuration; | |
7 | # but it assumes (and checks at the beginning) that networkd is not currently | |
8 | # running. | |

10 | # This can be run on a normal installation, in QEMU, nspawn (with | |
11 | # --private-network), LXD (with "--config raw.lxc=lxc.aa_profile=unconfined"), | |
12 | # or LXC system containers. You need at least the "ip" tool from the iproute | |
13 | # package; it is recommended to install dnsmasq too to get full test coverage. | |
14 | # | |

15 | # ATTENTION: This uses the *installed* networkd, not the one from the built |
16 | # source tree. | |
