Only 15y - BSD (Unix) much much longer around than Linux...

I thought Linux had been around for longer than that?

Linux was written in 1991 yes, but it was stable in 1994.
Between those years, it was Linus Torvalds writing the kernel in his own time, and was later joined by others, which speed up the process.

Maybe you're confused with UNIX, which is from 1971.

also, if i recall, the first linux kernel was based on minix, yes? no?

even then, the linux kernel underwent a complete rewrite at least once before linux 1.0 so is it even the same kernel? i wonder how many of those 10 million lines in linux 2.6 have survived from 1.0. Not many i'd hope. Also, look how much larger linux has got over the years, is that a good sign?

Inspired is a better word.

yes, i know no minix code could have survived wo the point when linux was put under the GPL, but didn't it have minix code in to start with? maybe not.
