From 9b93a986a68502c1ab2303efd7469fda0c5709cf Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Thu, 7 Apr 2016 10:58:06 -0400 Subject: [PATCH 143/216] Revert "reopen SNP protocol for exclusive use by grub" I *think* this should have been replaced by upstream's 49426e9fd2e562c73a4f1206f32eff9e424a1a73, so I'm reverting for now. May resolve rhbz#1273974.
