[Persistent home] How to increase [SOLVED]

[Béèm]

So I went to Konsole in SU mode.
Mounted the old knoppix.img at /media/knoppix_old and performed the command.
This is what comes on the Konsole.

root@3[knoppix]# cp -a /media/knoppix_old/* /
cp: cannot overwrite non-directory `/etc' with directory `/media/knoppix_old/etc'
cp: cannot overwrite non-directory `/home' with directory `/media/knoppix_old/home'
cp: cannot overwrite non-directory `/lib' with directory `/media/knoppix_old/lib'
cp: cannot overwrite non-directory `/lost+found' with directory `/media/knoppix_old/lost+found'
cp: cannot overwrite non-directory `/root' with directory `/media/knoppix_old/root'
cp: cannot overwrite non-directory `/tmp' with directory `/media/knoppix_old/tmp'
cp: cannot overwrite non-directory `/usr' with directory `/media/knoppix_old/usr'
cp: cannot overwrite non-directory `/var' with directory `/media/knoppix_old/var'
root@3[knoppix]#

I expected some trouble like this.
Apparently I didn't catch the procedure yet to get my old knnoppix.img into the system after having created a new and bigger one.
