    attachment is vsftpd.conf. The chroot lines are commented out. With this
    file, vsftpd runs fine, but if uncommented line
    chroot_local_user=NO
    chroot_list_enable=YES
    chroot_list_file=/etc/vsftpd.chroot_list (This is set by default if
    chroot_list_enable=YES

    then after starting vsftpd, /sbin/service vsftpd status will give error
    message *"vsftpd dead but subsys locked".
    *Any idea?
