[Bug 1708166] Re: systemd/udev does not rename network interfaces specified in .link files
Hell, believe or not, I had read along man system.link several times, but I would wish to be able to understand all these little subtleties. "All link files are collectively sorted and processed in lexical order, regardless of the directories in which they live. However, files with identical filenames replace each other. Files in /etc have the highest priority, files in /run take precedence over files with the same name in /usr/lib." Go figure... There are plenty of recipes on the Internet telling the reader to disable the damned "novelty" https://askubuntu.com/questions/767786/changing-network-interfaces-name-ubuntu-16-04 https://serverfault.com/questions/837454/interface-will-not-rename-under-systemd etc https://www.google.com.ua/search?q=ubuntu+systemd+link+rename+interfaces Most often, what is forgotten, is regeneration of initramfs file after .link changes But also, sometimes numeric prefix of the .link file name is forgotten as well So, this is not working, frustrating, infuriating the user and making him want to disable the damned thing altogether. As for me, just now, I managed to guess that .links preventing renaming of VLAN interfaces should have earlier prefixes than ones binding known interface names to their MAC addresses (as VLAN iface has the same MAC) This was a really hard-earned knowledge because there are no usable HOWTOs about these "novelties" https://askubuntu.com/questions/791149/prevent-vlan-and-bridge-interface-rename-to-renamex-form https://www.prolixium.com/blog?id=1023 https://www.google.com.ua/search?q=ubuntu+systemd+vlan+link+rename So, with current system documentation, unless you don't have an existing working sample for copying, you are doomed to guessworks, spitting and cursing until you guess what to write where and how to name it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708166 Title: systemd/udev does not rename network interfaces specified in .link files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1708166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708166 Title: systemd/udev does not rename network interfaces specified in .link files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1708166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1708166] Re: systemd/udev does not rename network interfaces specified in .link files
steps 1) and 2) really helped me to make this work now I am wondering where in the Ubuntu documentation I could find about this ? I see similar questions on the Internet, with most responses like 'revert to the old way of /etc/udev/rules.d/70-persistent-net.rules', 'disable net.ifnames', 'link /dev/null into /etc/udev/rules.d/80-net- setup-link.rules', etc. Only here on Launchpad I was able to get the proper and working response from you How did you learn about doing this right ? :> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708166 Title: systemd/udev does not rename network interfaces specified in .link files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1708166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Only the first link file will be applied and the rest will be ignored. .link files are copied into the initramfs, as udev is started there. Could you please try: 1) rename eth0.link to 00-eth0.link 2) update initramfs, e.g. $ sudo update-initramfs -u 3) reboot and check if you get expected behaviour. If you still do not get the names you want, then please attach the output of: $ udevadm info -q all -p /sys/class/net/enp2s0 ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708166 Title: systemd/udev does not rename network interfaces specified in .link files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1708166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
