Local: $ man systemd.link Ubuntu any release: http://manpages.ubuntu.com/cgi- bin/search.py?q=systemd.link
Upstream latest: https://www.freedesktop.org/software/systemd/man/systemd.link.html ... The first (in lexical order) of the link files that matches a given device is applied. Note that a default file 99-default.link is shipped by the system, any user-supplied .link should hence have a lexically earlier name to be considered at all. In general all systemd commands and units are documented. E.g. $ man systemd.service systemd.path systemd.link systemd.network and so on and so worth should give you authoritative documentation about every little detail. ** Changed in: systemd (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1708166 Title: systemd/udev does not rename network interfaces specified in .link files Status in systemd package in Ubuntu: Invalid Bug description: $ ip link show ... 2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether d0:50:99:76:a1:bf brd ff:ff:ff:ff:ff:ff $ cat /etc/systemd/network/eth0.link [Match] MACAddress=d0:50:99:76:a1:bf [Link] Name=eth0 I am pretty sure that MAC addresses do match And I don't change net.ifnames to 0 : $ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.4.0-87-generic.efi.signed root=/dev/mapper/vg_smart-root_smart ro then : $ sudo udevadm test-builtin net_setup_link /sys/class/net/enp2s0 [sudo] password for mwg: calling: test-builtin === trie on-disk === tool version: 229 file size: 6841778 bytes header size 80 bytes strings 1755242 bytes nodes 5086456 bytes Load module index timestamp of '/etc/systemd/network' changed Parsed configuration file /etc/systemd/network/eth0.link Parsed configuration file /lib/systemd/network/99-default.link Created link configuration context.

(and, surely, the interface is renamed from eth0 to enp2s0 on boot, but not renamed back afterwards) can you please tell where I could be wrong ? on my existing systems I still keep MAC->ifname relations in /etc/udev/rules.d/70-persistent-net.rules inherited from past Ubuntu versions. But this is a new setup of Ubuntu 16.04 and I would like to configure it in the new & recommended way. thanks in advance for your replies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1708166/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
