What everyone's up to

Last weekend I spent much longer than I should have building the smallest possible Linux image that will run my garage door monitor application on a Raspberry Pi W. It started off at 35Mb and ended up at 12Mb, completely through custom kernel configuration. Some of the things my kernel no longer has:

  • USB
  • Sound card support
  • Input device support (keyboard, mouse, joystick)
  • Ethernet
  • IPv6
  • Netfilter
  • BFP
  • Disk based file-systems (ext3, fat, etc.)
It retains enough to still be able to get on the Wi-Fi and run my application. There might be more that I could disable but I think it's small enough.
