From d59cc79e00e74184d42aec8743d57441c6b734bc Mon Sep 17 00:00:00 2001 From: Philip Prindeville Date: Sat, 16 Sep 2017 10:16:29 -0600 Subject: [PATCH] kexec-tools: issue warning when dd'ing vmcore With no warning, it just looks like the box has hung during boot. We don't want users resetting it without having captured a crashdump.
