CONFIG_DEBUG_FS appears to be a relevant to kernel development. So, turning that off should be fine for me. The below are from grep SELECT. Looking each up, none seem to enable DEBUG/TRACE elsewhere. However I am still somewhat a newbie. CONFIG_PROCESSOR_SELECT= CONFIG_B44_PCI_AUTOSELECT= CONFIG_B44_PCICORE_AUTOSELECT= CONFIG_B43_PCI_AUTOSELECT= CONFIG_B43_PCICORE_AUTOSELECT= CONFIG_B43LEGACY_PCI_AUTOSELECT= CONFIG_B43LEGACY_PCICORE_AUTOSELECT= CONFIG_MEDIA_SUBDRV_AUTOSELECT= CONFIG_INTEL_SPEED_SELECT_INTERFACE= If interest are the keys for grep LEGACY or _LEGACY which, semantically, I would hope to be able to turnoff/disable on hardware more current than perhaps 3-5 years ago or a KVM or VirtualBox VM. Your thoughts and input are appreciated.
