Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1514013

Description of problem:
When deploying an Atomic Host machine (at least version 7.4.2) from Satellite, the ostree setup is wrong. This means 'atomic host upgrade' throws an error.

Version-Release number of selected component (if applicable):
Satellite 6.2.12, Atomic Host 7.4.2.

How reproducible:

Steps to Reproduce:
1. Install Satellite 6.2.12, sync in the current version of Atomic Host kickstart (which is 7.4.2)
2. install Atomic Host on new machine
3. Log into the new machine, run 'atomic host upgrade'

Actual results:
Error is thrown:
error: /install/ostree: opendir(/install/ostree): No such file or directory

Expected results:
Machine is upgraded without issues.

Additional info:
Problem seems to stem from a change in the way subscription-manager handles ostree setup during deployment, in combination with the kickstart template in Satellite 6.2.12.

Workaround:
As a workaround, it's possible to run the following on the new machine to re-enable upgrades:

ostree remote delete rhel-atomic-host
ostree admin set-origin rhel-atomic-host-ostree https://very_long_satellite_url rhel-atomic-host/7/x86_64/standard
