Comment 1 Micah Abbott 2020-09-18 13:32:26 UTC 
We have a "quickfix" in place for the parent BZ, this BZ is going to track the more complete fix in 4.7
Comment 2 Luca BRUNO 2020-10-21 11:09:58 UTC 
The better fix for this landed in https://github.com/coreos/afterburn/releases/tag/v4.5.2, which will head to RHCOS 4.7 soon.

The Ignition side of this same issue is tracked at https://github.com/coreos/ignition/issues/1092 but currently stalled on the upstream library.
Comment 3 Luca BRUNO 2020-11-13 08:01:02 UTC 
Final update from the RHCOS pipeline: Afterburn v4.5.3 (which contains the fix for this) just landed in RHCOS 47.82.202011122343-0.
Comment 6 jima 2020-11-19 08:29:28 UTC 
Used 47.82.202011122343-0 to deploy upi on vsphere with version 4.7.0-0.nightly-2020-11-18-203317, and enabled secureboot when booting instance. 
The installation is successful. so move the bug to VERIFIED.
