I use the usermode emulation fairly extensively for cross development/testing.
User emulation has three main advantages for our purposes:
- It's significantly faster than full system emulation, especially when the
target system would be using an NFSroot.
- It doesn't rely on a target kernel. These frequently have bugs, especially
on the less popular architectures..
- It's much easier to integrate into test harnesses. With binfmt_misc it's
mostly transparent. For full system emulation you have to mess about with
telnet/rsh.
The main downside is that threaded applications don't currently work properly,
but that's fixable.
