Move root file system to new partition

find / -xdev -print0 | cpio -pa0V /mnt/temp

cd boot; find ./ -xdev -print0 | cpio -pa0V /mnt/temp/boot

grub-install --root-directory=/mnt/hda1 /dev/hda

-xdev   Don't descend directories on other filesystems.

-print0
        True; print the full file name on the standard output, followed by a null character
        (instead of the newline character that -print uses).  This allows file  names  that
        contain  newlines or other types of white space to be correctly interpreted by pro‐
        grams that process the find output.  This option corresponds to the  -0  option  of
        xargs.

-p	(pass) cpio -p reads the standard input to obtain a list of
        path names of files.

-a	Reset access times of input files after they have
        been copied. Access times are not reset for linked files
        when cpio -pla is specified (mutually exclusive with -m).

-0      A list of filenames is terminated by a null
        character instead of a newline

-V	Special verbose. Print a dot for each file read or written.
        Useful to assure the user that cpio is working without
        printing out all file names.
