Description Akshay Jain 2017-11-20 01:58:35 UTC
Description of problem:

NetworkManager-wait-online.service is occasionally completing (aka Started) before network connectivity is established, thus allowing systemd to reach the network-online.target before connectivity has been established.

Customer use autofs and LDAP heavily and depend on the network connectivity being established before those services are brought up. When network connectivity is not up and autofs is started, the host is unable to properly boot.

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

How reproducible:
Activate NetworkManager-wait-online.service and boot.

Additional info:
 if customer override the NetworkManager-wait-online.service to execute `ExecStart=/usr/bin/nm-online --timeout 30` instead of `ExecStart=/usr/bin/nm-online -s --timeout 30`, the issue no longer occurs.

We have a bug open on upstream with same issue.
