ubuntu/ipa ramdisk cannot be boot successfully

When we use the ramdisk created based on the "ubuntu" and "ironic-agent" elements to boot a baremetal server with ironic agent-ilo driver, the OS cannot be boot successfully. Below are the detailed console log:

    Contains the directory name of /sys and /proc

    When a ubuntu/IPA ramdisk is used to boot a baremetal machine with
    ironic agent-ilo driver, it fails at the point of mounting /proc
    and /sys. After the vmlinuz(kernel) is started and it tries to
    load the partitions on ramdisk. It need the directory of "/sys"
    and "/proc" to mount the corresponding filesystems.
    In order to fix this issue, the directories of "sys" and "proc"
    are retained but the subdirectories or files under them are empty.
    With this change, the directories of "/sys" and "/proc" shows
    up in the ramdisk and kernel will mount sys and proc filesystems
    on them respectively.
