Consider not download automatically (all) kernel modules

moul commented 8 years ago

On some kernels, we have about 470MB of optional kernel modules.

On the on the Alpine Linux image, it is ridiculusly 15 times higher than the 30MB original image size :flushed:.

Potential ways of optimization:

disable some loadable kernel modules
build more loadable kernel modules in the kernel (seems smaller in size when built-in)
do not call the sync-kernel-modules automatically but document it
find a way to "lazy-download" needed kernel modules
mount /lib/modules as a read-only network block device/nfs
use a compressed file system for /lib/modules

@ElNounch, you're awesome

Thank you for this PoC, we will discuss it internally, but I clearly like the idea

And thank you for the other non-POC related updated (typos, init script headers)
