Description Javier Martinez Canillas 2018-08-03 14:30:04 UTC 
Description of problem:

When adding the rd.neednet=1 parameter to the kernel command line on a system that either has no wired interface or an interface without its carrier signal present, dracut enters into an infinite loop caused by the /lib/dracut/hooks/initqueue/finished/wait-network.sh script.

Version-Release number of selected component (if applicable):

dracut-048-14.git20180726.fc28.x86_64

How reproducible:

Easy

Steps to Reproduce:
1. Generate a initramfs with the mentioned dracut version
2. Add the rd.neednet=1 parameter to the kernel command line
3. Boot a machine that doesn't have a wired network interface with its carrier signal present.

Actual results:

Dracut enters into an infinite loop and the system does not boot.

Expected results:

The system should always boot when adding rd.neednet=1 to the kernel command line parameters.

Additional info:

The regression was introduced by the following upstream commit:
