Cause: hostname from vSphere metadata was not set before NetworkManager started Consequence: due to a change in NetworkManager priorities this metadata was ignored when hostname was set Fix: hostname is now being set by `vsphere-hostname.service` before NM starts, if this information is available in vSphere metadata Result: vSphere node hostname is correct

Description Vadim Rutkovsky 2020-12-06 18:04:35 UTC 
+++ This bug was initially created as a clone of Bug #1904824 +++

Description of problem:
In Fedora 33, a change was introduced to set the hostname to "fedora" as a fallback instead of the default "localhost", so the current script does not work in OKD as NM will assign the fallback hostname.

This change makes it so the hostname is set to vSphere's
guestinfo.hostname if that's defined, before NetworkManager is started.
