The title says it all. I want to install Ubuntu (specifically Lubuntu for now, but maybe another flavor later) to a raw loopback image file (IMG, not ISO).
The image file will reside on my FAT32-formatted USB stick at the maximum allowed size: 4,294,967,295 (or 2³²−1) bytes. (FAT32 is for Grub4Dos compatibility.)
I know Wubi/Mint4Win does something like this inside Windows, so I know it's possible; I've just never found a good resource that clearly documents the process.
Any help would be much appreciated! Thanks!
