Yeah, figuring out that "cd /usr/blah" ends up in /emul/aout/usr/blah while
"cd / and cd usr/blah" ends up in /usr/blah took me a bit on a recent

I think if this behavior was configurable some how it would be nice.
Or even use the (FreeBSD?) method of having a "linux" (or whatever) binary
that does the right thing. e.g. 'linux netscape' to launch netscape with
the option of searching /emul/linux or not. Adding the jail() syscall
might be useful for this also. e.g. In some cases you want an emulated
binary to _only_ have access to /emul/whatever.
