From 9ab2c149c2e79e11d5fa21fcfdf546d7774210c4 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Tue, 15 Aug 2023 09:26:06 +0200 Subject: [PATCH] s390/ipl: add missing secure/has_secure file to ipl type 'unknown' 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.
