The odd thing is, that seems like the obvious answer. However, if you
take only the first two lines:

Dir.chroot(Dir.pwd)
Kernel.system('echo "new file" > foo')

I'd expect that to work, because 'echo' is a builtin on most shells.
But it doesn't, not on a random debian box I just tried. I don't
understand that.
