Description David Caro 2016-04-28 07:50:30 UTC

Description of problem:
When disabling network manager, if there were no 'DEVICE' options defined in the /etc/sysconfig/network-scripts/ifcfg-ethX files, the network fails to start 

Version-Release number of selected component (if applicable):
# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 

# rpm -qf /etc/sysconfig/network-scripts/ifup-eth
initscripts-9.49.30-1.el7.x86_64


How reproducible:
Get a CentOS 7.2 basic installation (I used virt-builder centos-7.2), disable NetworkManager, and run 'service network restart'

Steps to Reproduce:

3.

Actual results:
It fails complaining that the 'device' does not seem to be present

Initscripts need either DEVICE or HWADDR.

Comment 5 Jan Macku 2019-10-24 15:17:46 UTC

I'm not able to reproduce this issue. It works in current release of dracut.

If it's still issue for you please send us logs with set parameter "rd.break" on kernel cmd.
