If I am right, the softmmu/system build target for each
architecture subsumes the source of the user target. It's what I see in the
build of i386. But then, I think the user targets have some dedicated user
layer which allow a foreign architecture user binary to be relayed through
in order to map to the host. What I was wondering is, if the user layer of
qemu is used by the user target, and by user layer I mean the using
contents of linux-user, then how does the system target receive the user
programs instead of the qemu user emulation layer even within a guest that
is an entire OS?
