And I can't see what are the benefits of having a 25GiB FAT32 loop file in a 27GiB ext3 partition instead of a 25GiB FAT32 partition and a 2GiB ext3 partition. Before you say "dynamically resizable!" consider that for me the only difference is that with the loop file method I won't have to use e2resizefs (but I'll have to use a tool to resize the FAT32 filesystem either way).
