Action Item #231
kernel config cleanup
|Status:||In Progress||Start date:||14 Oct 2013|
|Category:||03 - Linux Kernel|
|Target version:||1.1.0 - Upgrades|
|Severity:||04 - Low|
To improve boot time, the kernel config should be examined for which drivers could be made modules and loaded at boot time. Module loading could be done by specific init scripts as needed or by a specialized init process that parallelizes the init scripts (without using scripts to reduce fork/exec overhead).

- wlan0 takes 8 seconds to load

Bumping this to 1.1.0 release because the kernel config has so much cruft in it that PiBox just doesn't need, like all those eth drivers. This is because I switched, a while back, to using the defconfig for the Pis. Now I need to switch back to a trimmed down kernel so save both disk and memory space.
