Not funny to me. I think it's valuable work.

My old laptop has about 1000x the bogomips and 1000x the memory shown in 
your console log. Your work shows me what 1000 virtual machines might look 
like here.

Shrinking the operating system in that way (no block layer, no network 
stack etc.) is important work and is a real step towards comfortably 
hosting a million busy containers on a single system.
