create_compressed_fs(1)

NAME
create_compressed_fs, extract_compressed_fs — convert and extract a filesystem to/from a cloop volume

SYNOPSIS

create_compressed_fs image blocksize [> image.cloop_compressed]

extract_compressed_fs filename

DESCRIPTION

create_compressed_fs compresses a filesystem image to a compressed image suitable for mounting with the cloop driver. blocksize must be a multiple of 512 bytes. Make sure you have enough swap to hold the entire compressed image in virtual memory! Use "-" as filename to read data from stdin, as in:

mkisofs -r datadir | create_compressed_fs - 65536 > datadir.iso.compressed

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
