[systemd-devel] container virtual Ethernet link naming

[Johannes Ernst]

man systemd-nspawn, section on --network-veth
    "The container side of the Ethernet link will be named <literal>host0</literal>."

container> ip link
...
2: host0 at if9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether ce:d3:4f:6c:44:5f brd ff:ff:ff:ff:ff:ff link-netnsid 0

Where does the @if9 come from, and what’s the naming scheme here?

Cheers,



Johannes.
