Comment 2 for bug 400241

Fixed in Upstart 0.6.1:

0.6.1 2009-07-16 "Born in the wagon of a travelling show"

        * D-Bus 1.2.16 is now required.

        * Updated ptrace() code to handle receiving the trapped stopped
          child _before_ we receive the trapped fork() syscall, which
          seems to be the most common way the race goes when running
          as init. This seems to make "expect fork/daemon" largely work.
          (Bug: #264711)

        * runlevel will now output "unknown" and exit with an error when
          called before the first telinit call. (Bug: #400248)

        * runlevel will prefix error messages with the utmp filename being
          used. (Bug: #400241)
