  Changed paths:
    M lib/libc/sys/jail.2
    M sys/kern/kern_descrip.c
    M sys/kern/kern_jail.c
    M sys/sys/filedesc.h

  Log Message:
  -----------
  When a process, such as jexec(8) or killall(1), calls jail_attach(2)
to enter a jail, the jailed root can attach to it using ptrace(2) before
the current working directory is changed.
