[fuse-devel] treating partitioned files as disks

[Eric S. J. <es...@ha...>]

I have a project (ipcop) where I am trying to create a flash image and 
then modify it slightly multiple times for each instance where it is used.

the code currently though some really ugly things in that it creates a 
file for every partition so I can format, copy data etc. and then uses 
dd to merge everything together into one big happy flash image.

Needless to say, as soon as you modify anything, "things break".

I am looking for some way to treat a file as if it were a block device 
so I could format, impose filesystem, and then mount it so I can copy 
all of the files in place and hit it with grub to make it bootable.

Is this something fuse can do easily?  Already?  I think this technique 
would also be useful in producing partitioned CD-ROM images.

Appreciate your assistance.
