Issue 1:
Maybe change up variable naming to keep more in line with sysfs/DMI standards ?
as future reference: [1]
on my normal(?) Intel ATX motherboard both sysfs entries are empty
but board_name & board_vendor exist: I might expect to get
/tmp/sysinfo/board_name
from board_* and not from the sys_* or product* domain
cat /sys/devices/virtual/dmi/id/board_vendor
Intel Corporation
cat /sys/devices/virtual/dmi/id/board_name
DZ77RE-75K
Issue 2:
boardname can end with a dash in QEMU:
cat /sys/devices/virtual/dmi/id/product_name
Standard PC (i440FX + PIIX, 1996)
