How can Minix 3 be so small

[Hendrik Tews]

Hi,

I just noticed that the Minix 3 kernel is under 4000 lines. I
couldn't easily find numbers for Pistachio, but I guess it is
comparable to Fiasco, which is about 15.000 lines (without the
kernel debugger).

Could anybody explain why Fiasco is so big in comparison with
Minix 3? From the difference in size I would expect that there is
an essential difference in the feature set between Minix 3 and
Fiasco. Or are the Minix lines just four times longer on average? 

Bye,

Hendrik
