Fuse Filesystem to mount a block device as a single image file
This allows tools like rsync to work with a block device
This currently only does the very bare minimum to function. Only mounts read only. Just sharing it here incase anyone else wants this, or wants to help develop. I couldn't find anything else on the web that allowed rsyncing a block device (apart from rsync patches which seemed somewhat flaky).
Disclaimer: I'm not a C programmer, so my code might not be the greatest :), but it's been working in production.
