Hi,
first of all thanks for bringing Rocky to life and all the fantastic work you do!
I’m preparing a stateless diskless installation with Rocky, i.e. a read-only nfsroot (not sure this is relevant though).
Almost everything is working fine to our needs - yet, I can’t get predictable network interface naming to work.
The journal says:
> Mar 18 00:38:28 systemd-udevd[618]: link\_config: autonegotiation is unset or enabled, the speed and duplex are not writable.
> Mar 18 00:38:28 systemd-udevd[618]: Error changing net interface name ‘eth0’ to ‘enp3s0’: Device or resource busy
> Mar 18 00:38:28 systemd-udevd[618]: could not rename interface ‘2’ from ‘eth0’ to ‘enp3s0’: Device or resource busy
Do I have to adapt the initramfs configuration?
Currently, I’m only doing:
> dracut --no-hostonly --nolvmconf -m “nfs network base” --xz /boot/initramfs.pxe-4.18.0-348.20.1.rt7.150.el8\_5.x86\_64 4.18.0-348.20.1.rt7.150.el8\_5.x86\_64
Thanks in advance!

Any ideas how I can try to debug that?

Adding **systemd** , **systemd-initrd** and **dracut-systemd** modules to the dracut build call fixed the issue.
That way the interface is renamed in the initrd stage **before** switching root.
I didn’t considered that as it was not necessary for RHEL 7.
