# steps

Two RHEL 8 boxes for internal component pipeline

## RHEL8,
* determine nic configs. Make RHEL8 hosts use RHEL7 style nic names.
* fix for the undercloud first

* ensure rhos-release -u

* overcloud image builds ( local )

# Current Situation of baremetal Machines:
@weshayutin @rlandy fyi.. please find current status of baremetal machines - OS and Nic naming convention.

# What to do?? **

Currently Environment are on different OS versions and releases.

I think we should first get to RHEL8.1 on all systems and then see if all machines have same or different naming convention. (HP and Dell naming convention can be different - more chances).

**Good reads(Default settings is good for good reasons):-**

- how default naming convention work - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/consistent-network-interface-device-naming_configuring-and-managing-networking
- Why its a bad idea to move back to eth* based naming convention(net.ifnames=0) - https://access.redhat.com/solutions/2435891
