Sped up build time for a 6 gb disk image file from 30 minutes to 30 seconds. Wow.

Sparse files are the shit. I made order-of-magnitude improvements to the build time of a yoctolinux build by sprinkling less than a handful of dd calls, conv=sparse parameters to existing dd calls and -S parameters to rsync calls. ❌ at 2017-07-26T09:17:44Z
