Hello all,
I have a small problem while working with create_compressed_fs tool. I downloaded KNOPPIX 5.1.1 iso, copy its content to my hdd. Then I extracted KNOPPIX compressed image by extracted_compressed_fs tool. The version of cloop I use is 2.05-1, because exactly this version is used in KNOPPIX 5.1.1. After extracting I try to compress this image (without mounting and modification of image!) by create_compressed_fs tool. But the size of new compressed image is 30Mb greater! I tried to use '-b' option - but no luck. Also I tried variouse block sizes, even 4Mb, the difference in size is less, but it's still about 15Mb.
Here is the commands:
$ cloop-2.05/extract_compressed_fs KNOPPIX > KNOPPIX.img
$ ls -l KNOPPIX
-rw-r--r-- 1 vass vass 723905561 Apr 12 17:25 KNOPPIX
$ ls -l KNOPPIX.img
-rw-rw-r-- 1 vass vass 2045902848 Apr 12 17:38 KNOPPIX.img
$ cloop-2.05/create_compressed_fs -b - 65536 < KNOPPIX.img > KNOPPIX-recompressed-65536-b
$ ls -l KNOPPIX-recompressed-65536-b
-rw-rw-r-- 1 vass vass 754331717 Apr 16 13:18 KNOPPIX-recompressed-65536-b
Can somebody explain me, why it happens?
Thank you,
Vasily.
