Hello !

with tools like losetup or dmsetup/kpartx, i can turn a flatfile/imagefile or parts of that into a blockdevice.

but how can i do that in reverse ?

for example make 80gb harddisk /dev/sda appear as 80gb /tmp/flatfile ?

ChunkFS from http://chunkfs.florz.de/ comes close to what i need, but Fuse is slow and ChunkFS doesn`t have write support.

any hints ?

regards
roland
