Name one such system. [1]

Hint: the path to env isn't going to change on a standards-compliant 
system for the same reason that /bin/sh is always found in the same 
place.  See IEEE Std 1003.x-2001 ("POSIX").

[1]: You might actually find a few very old, very broken versions of 
Linux which don't have a /bin/sh, only a /bin/bash.  I've heard such 
creatures may have a /bin/env rather than a /usr/bin/env, too.
