first i mounted img file to directory made some modifications but i could not pack the directory again
second i tried to mount img file to a hard drive (dev/sdb1) and did
dd if=/dev/sdb1 of=system.img
but this time system.img file size was long as partition size.. but longer than original system.img
than tried dd with to bs and count parameters but no success.
what is the point to pack system directory to img again?
