    Which other systems' manpages did you read? I found a few which did
    not specify what the new cwd should be, but also several which said
    that Linux's behavior was correct. For instance:

    SunOS 4.1.1: "The current working directory is unaffected by this call."

    SunOS 5.4 / Solaris 2.4: "The user's working directory is unaffected
    by the chroot() and fchroot() functions."

    IRIX 5.3: "The user's working directory is unaffected by the chroot
    system call."

    NetBSD 1.2: "It should be noted that chroot() has no effect on the
    process's current directory."

    Any questions?
