This bug was initially created as a copy of Bug #2161915

I am copying this bug because:

Also applies to RHEL8

Description of problem:

When restarting dbus.service unit, (due to failure, patching, etc.), we can see that NetworkManager.service unit just stops, causing network to be lost upon DHCP lease expiration.

Since NetworkManager has a hard dependency on dbus, it should restart or reconnect (better).

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

NetworkManager-1.40.0-5.el8_7.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Restart dbus.service unit

Actual results:

NetworkManager.service stops

Expected results:

NetworkManager.service still active
