create a compressed cloop volume

    		infile
    		outfile

## DESCRIPTION

`compressloop` compresses a filesystem image to a compressed image suitable for mounting with the cloop driver. blocksize must be a multiple of 512 bytes. This is a complete rewrite of create_compressed_fs which does not need as much swap to hold the entire compressed image in virtual memory, but also does not work in pipe mode anymore (i.e. you need real files as input and output).

You can specify the compression level, so it's possible to create a larger but faster image.

Please note that due to the lseek() calls, it is no longer possible to use stdout as output file. Those who want to use images to pipe them to a CD burner will still need the old create_compressed_fs utility.

## MOUNTING

You have to pass the options to the cloop module on loading:

insmod cloop.o file=/path/to/compressed/image

mount -o ro -t whatever /dev/cloop /mnt/compressed
