[SOLVED] Predictable network interface names disabled in 5.0.21-2?

[skywavecomm]

There was a new kernel update today/last night (9-19-2019) and it seems my servers' interface names reverted from ens0p0 to the old eth0 format. I don't have the predictable network interface names disabled in my grub startup parameters so why would it have reverted?

Thanks!

FYI, udev handles persistent nic interface names. You might might want to look there.

There are no udev rules in /etc/udev/rules.d.

That location is for system administrators, you mean /lib/udev

You might want to include pveversion --verbose in your post. Since stretch, there are no rules, udev handles this automatically. At least according too https://lists.debian.org/debian-user/2017/07/msg01453.html

Derp I'm dumb, looks like I transferred a systemd network config file of /etc/systemd/network/99-default.link into the server with the contents:

[Match]
Path=/devices/virtual/net/*

[Link]
NamePolicy=kernel database onboard slot path
MACAddressPolicy=none

Removing that and rebuilding the initramfs resolved the issue.
Thanks @lhorace for the help!
