   An update that has one recommended fix can now be installed.

Description:

   This update for biosdevname fixes the following issues:


   - Read DMI info rom sysfs. (bsc#1174491)

     A kernel with Secure Boot lockdown may prohibit reading the contents of
   /dev/mem, hence biosdevname fails. The recent kernel provides the DMI byte
   contents in /sys/firmware/dmi/tables/*.

   - Add buffer read helper using read explicitly.

     mmap can't work well with a sysfs file and it's required to read the
   contents explicitly via read, even if USE_MMAP is enabled.
