From 77e49091664430eb3ffda9ff0ce4083da91f8ce4 Mon Sep 17 00:00:00 2001 From: Dag Wieers Date: Thu, 21 Mar 2013 21:30:44 +0100 Subject: [PATCH] Implement python-dmidecode/dmidecode as alternative for kernel DMI This implementation falls back to python-dmidecode (RHEL5.5+) if the kernel as no DMI support. Alternatively, if python-dmidecode is missing, we attempt to use the dmidecode binary (for RHEL5.4 and older) before giving up. This fixes #376 and #1657 and also helps @lwade on RHEL5.5+. --- library/setup | 122 +++++++++++++++++++++++++++++++++++++------------- 1 file changed, 91 insertions(+), 31 deletions(-) diff --git a/library/setup b/library/setup index 44adf8231b..23be63865e 100644 --- a/library/setup +++ b/library/setup @@ -18,6 +18,7 @@ # You should have received a copy of the GNU General Public License # along with Ansible.
