Description Dmitry Morozovsky 2014-04-24 06:50:00 UTC

I suppose it would be useful to be able to track server hardware changes via
SMBIOS/DMI.

In my case, after replacing server RAM I could not find exact failed module by
serial number because did not save dmidecode output before memory swap.

The attached script should help in such and related situations. To enable
tracking dmidecode diffs in daily mail the admin should set the variable
daily_status_dmidecode_enable to "YES" in /etc/periodic.conf

Fix:
