to prevent eudev from renaming your network interface to some nonsense, the recommended method is to touch /etc/udev/rules.d/80-net-name-slot.rules with udev, the file name changes to /etc/udev/rules.d/80-net-setup-link.rules it would be very nice to rename the file on update or at least mention it in the news item before people are left with network machines unaccessible (yes, I have one 60 km away from me without anyone competent to fix it in reach ...:-( ) Reproducible: Always
I think we recommend using the kernel config option but if the new filename works, I don't see a problem with moving it in pkg_postinst. I'm sorry for the inconvenience.

I could add a warning to the ebuild. I don't really want to do a rename without user interaction because that would cause a change in behavior for people who have already switched, but maybe forgot to remove the old rules file. Also, I updated the wiki with the instructions provided by systemd.

So it turns out that we already emit a warning when switching from eudev to udev: > if [[ ${HAD_EUDEV} -eq 1 ]] ; then > ewarn > ewarn "${P} defaults to predictable interface renaming, as described in the URL below:" > ewarn "https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames" > ewarn > ewarn "If you wish to disable this, please see the above documentation, or set" > ewarn "net.ifnames=0 on the kernel command line." > fi I suppose it would be safe to rename the file under the same conditions (eudev -> udev).

I'd totally forgotten about this (although I think it was part of why I suggested it initially). Yeah, let's do that.
