Package: dmidecode
Version: 3.0-2~bpo8+1
When I invoke `dmidecode -s` and any viable argument I get the
information output to me twice.
Here is a transcript:
# dmidecode -s bios-vendor
American Megatrends Inc.
American Megatrends Inc.
# dmidecode -s processor-manufacturer
Intel(R) Corporation
Intel(R) Corporation
Here is a transcript when invoking the same command with `strace`:
# strace dmidecode -s bios-vendor
