  please don't. mucking around with v0.01 of linux might be
entertaining from a historical perspective but it won't have much
value in making you more hireable. :-)

  just pick a specific topic somewhere in the kernel and dig into it.
and make sure you learn git so you can use "git log" to follow along
so you can see the ongoing development as well.
