From 482e8050aab4ad10bcd64241f1a9b540463b3274 Mon Sep 17 00:00:00 2001 From: John Johansen Date: Fri, 5 Feb 2021 04:56:02 -0800 Subject: apparmor: don't create raw_sha1 symlink if sha1 hashing is disabled Currently if sha1 hashing of policy is disabled a sha1 hash symlink to the non-existent file is created. There is now reason to create the symlink in this case so don't do it.
