If anyone has any objections, please let me know. ------------------ From: Sven Schnelle commit ea5717cb13468323a7c3dd394748301802991f39 upstream. OS installers are relying on /sys/firmware/ipl/has_secure to be present on machines supporting secure boot. This file is present for all IPL types, but not the unknown type, which prevents a secure installation when an LPAR is booted in HMC via FTP(s), because this is an unknown IPL type in linux. While at it, also add the secure file.
