Hello,

Re:

Are there any upcoming plans for turning off the use of legacy interface names in the next official CentOS 7.x AMI?

Currently, both the official RHEL 7.3 GA AMI and the latest available official CentOS-7 x86_64 AMI use legacy interface names via either:

– “net.ifnames=0” kernel boot parameter or
– “ln -vs /dev/null /etc/udev/rules.d/80-net-setup-link.rules”

As I’m setting up some automation which will use the official CentOS 7 AMI, I’m wondering whether to switch on the new naming scheme manually and pre-empt the switch over or wait until the official AMIs switch over.

Also, will the next CentOS 7 AMI start using NetworkManager instead of the traditional ifcfg-* scripts?

Regards, Jinesh

  • Jinesh, I think CentOS still stay on ifcfg-* fashsion. For network manager, it is optional for networking in CentOS. For AMI, I think you should stay for a while until it is no longer present in kernel.
