4 GB size limit imposed on some virtual disks

[dnoblet]

When virtual disks are hosted on some types of volumes that have small limits on file sizes (such as the 4 GB limit on FAT32), it is not possible to create a virtual disk that exceeds this limit on such a volume (even though the Wubi installer does not prevent the user from selecting a size that is larger than the given limit). As it stands now, if a user does try to select a larger size, the Wubi installer will silently fail and create a smaller virtual disk.

At the very least, the Wubi installer should detect such a scenario and disable these larger-sized choices in the installer. However, a better solution would be to create multiple virtual disk files whose aggregate size is that of the desired volume; then, tie them together using LVM (or some other similar tool).

Wubi does create multiple virtual disks in this case, you should probably see a usr.disk for instance.

Right. But, the total amount of space is still not necessarily what the user asked for. Also, this solution is suboptimal in that you do not present the space as a single partition (i.e. you might have 4 GB in "/usr/" and 4 GB in "/lib", etc.).
