The biggest issue I have with genext2fs is that it currently allocates RAM for the complete image, which in my case will cause it to swap and for other users cause it to crash, since image > (ram + swap). Fixing the memory issue before the release would be greatly appreciated.

What about putting it on the shortlist for backports after the release? That should give us all more time to test it and eventually get into the hands of stable branch users. Of course I'd still prefer it to go in before the release and backport fixes :)
