    8. 필요에 따라 partitioning을 한다.
       (단위는 쉽게 Giga Byte를 사용한다.)
       7번 (/export/home)은 0번부터 6번을 지정하고 나머지 값을 자동으로 갖게된다.

Enter size of partition '0' [0b, 0c, 0.00mb, 0.00gb]: 1gb    => /
Enter size of partition '1' [0b, 0c, 0.00mb, 0.00gb]: 1gb    => swap

    9. 지정값을 확인하고 맞으면 yes를 선택한다.

    10. table name을 설정해 준다.

Enter table name (remember quotes): backup

    11. disk를 label 할 준비가 되어 있으면 yes를 선택한다.

    13. 위와같이 "Tag"부분이 엉망인것을 볼 수 있다, Tag를 설정 하려면 아래와 같은
        partition menu에서 Tag를 수정할 slice를 선택하여 준다.

PARTITION MENU:
        0      - change `0' partition
        1      - change `1' partition
        2      - change `2' partition
        3      - change `3' partition
        4      - change `4' partition
        5      - change `5' partition
        6      - change `6' partition
        7      - change `7' partition

ex)

Enter partition id tag[unassigned]: var    => tag 수정
Enter partition permission flags[wm]:     => permission은 default값을 사용
Enter new starting cyl[1678]:         => starting cyl는 전 partition의 끝 cyl값보다 1 많게 하여 쓴다
Enter partition size[2099178b, 839c, 1024.99mb, 1.00gb]: => partition size는 default값을 사용

    14. 설정이 변경 되었는지 확인한다.

    15. label menu를 선택하여 설정을 저장한다.

partition> la
Ready to label disk, continue? y

    16. partition utility에서 빠져 나온다

partition> q

    17. newfs utility를 사용하여 target disk에 새로운 file system을 생성한다.
        (각 slice별로 해줘야 함)

[aculab:/export/home/aculab]# newfs /dev/dsk/c0t3d0s5
newfs: construct a new file system /dev/rdsk/c0t3d0s5: (y/n)? y

[aculab:/export/home/aculab]#

    18. ufsdump를 실행시킬 partition을 mount 시킨다.
            (mount point는 아무거나 사용 가능, 여기서는 /mnt를 사용한 예를 들고 있다)

#[aculab:/export/home/aculab]# mount /dev/dsk/c0t1d0s0 /mnt    => target disk의 5번째 slice를 /mnt에 mount 시킴

#[aculab:/export/home/aculab]# ufsdump -0f - /dev/rdsk/c0t0d0s0 | ( cd /mnt; ufsrestore xf - )

    ** 위에서 /dev/rdsk/c0t0d0s0는 source disk의 partition이고
       /mnt 로 표현된 곳은 target disk가 mount 되어있는 mount point이다.

    ※ partition dump가 끝난 후 나오는 두개의 질문에는 "NO"로 대답한다.

        set owner/mode for '.'? [yn] set owner/mode for '.'? [yn] n
        Directories already exist, set modes anyway? [yn] n

    19. 위와같이 각 partition별로 ufs dump 를 실행시킨다.

    20. boot 블록을 카피 한다.

#[aculab:/export/home/aculab]# /usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0            <- sparc
 
#[aculab:/export/home/aculab]# /usr/sbin/installboot /usr/platform/i86pc/lib/fs/ufs/bootblk /usr/platform/i86pc/lib/fs/ufs/pboot /dev/rdsk/c1d0s0       <- intel(x86)

    ** space에 주의!!! 명령어 마지막 부분의 /dev/rdsk/c0t1d0s0는 target disk의 root 영역이다.

    이걸 안해주면 disk 부팅이 안됨!!!

    21. 마지막으로 target disk의 root영역을 다시한번 mount 시켜 /etc/vfstab 정보를 바꾸어 준다.

[aculab:/etc]# vi vfstab
"vfstab" 12 행, 477 문자
#device     device      mount       FS  fsck    mount   mount
#to mount   to fsck     point       type    pass    at boot options

fd  -   /dev/fd fd  -   no  -
/proc   -   /proc   proc    -   no  -
/dev/dsk/c0t0d0s1   -   -   swap    -   no  -
/dev/dsk/c0t0d0s0   /dev/rdsk/c0t0d0s0  /   ufs 1   no  -
/dev/dsk/c0t0d0s6   /dev/rdsk/c0t0d0s6  /usr    ufs 1   no  -
/dev/dsk/c0t0d0s5   /dev/rdsk/c0t0d0s5  /var    ufs 1   no  -
/dev/dsk/c0t0d0s7   /dev/rdsk/c0t0d0s7  /export/home    ufs 2   yes -
swap    -   /tmp    tmpfs   -   yes -

    이곳에서 모든 target 번호를 0에서 1로 수정해준 후, 저장하고 빠져 나온다.
