Verified with Sat6.3 snap 20.

1) Setup PXE provisioning, auto provisioning [1]
2) On a machine within Capsule's subnet, boot from PXE, going into Foreman Discovery Image
3) Press Enter before it sends facts, set own fact: "kexec = true"
4) Send the facts
5) Start sshd, connect to it, verify that files /lib/modules/*/kernel/drivers/gpu/drm and /lib/firmware/{amdgpu,radeon} do not exist
6) From Satellite WebUI, autoprovision this discovered host (Hosts -> Discovered Hosts -> Auto Provision All)
7) If it kexecs and survives until system installation, the bug is fixed

^ Tried with Cirrus, QXL, VGA video drivers.
