Is it safe to set net.ifnames=0 in RHEL7, RHEL8 and RHEL9?
Issue
- Is it safe to disable Consistent Device Naming by setting net.ifnames=0 on the kernel command line in RHEL7, RHEL8 and RHEL9?
- Why can I no longer use the 70-persistent-net.rules file to force persistent ethX names like I could in earlier versions of Red Hat Enterprise Linux?
Environment
- Red Hat Enterprise Linux 9
- Red Hat Enterprise Linux 8
