Changing to "old" interface naming during pxeboot/kickstart

[supertight]

I know this is probably a dumb question. But for some reason, I'm just not seeing it.
I've been searching for it, an I have found some stuff.
I know I need to add "net.ifnames=0" and "biosdevname=0" somewhere. But where?

I want the machines to pxe/kickstart/install with the interface as "eth0" not "enp0s25"

What am I missing?

Thanks for reading.

On the kernel command line. It's a FAQ - http://wiki.centos.org/FAQ

In CentOS 7, you need to modify this file: /etc/default/grub

Then edit the line:

Code: Select all

GRUB_CMDLINE_LINUX="crashkernel=auto rhgb console=ttyS0,19200n8 net.ifnames=0"

In CentOS 7, ...

The question is about PXE boot, not about ordinary CentOS.

PXE boot receives from DHCP info about a TFTP server that has syslinux and kernel(s).
The syslinux has a menu (similar to GRUB). If one sets up default TFTP&syslinux on CenOS
server, then menu is usually in file /var/lib/tftpboot/pxelinux.cfg/default
Commad line options, like the kickstart, are stored in that file.

PS. The syslinux above is for legacy BIOS PXE. UEFI PXE has slightly different details.

I know I need to add "net.ifnames=0" and "biosdevname=0" somewhere. But where?

You have set up the PXE and kickstart, have you not? Then you know where your TFTP share is.
