If it quaks like a disk image, it is a disk image
- duskwuff 1y agoA filesystem is not a file. (Yes, you can store a filesystem in a file - and that's a trivial sort of disk image, but one with some serious drawbacks like "you have to allocate all of the space up front". We can do better.)
- Dylan16807 1y agoSome of the most popular disk image formats are basically a sparse file abstraction for non-sparse files and nothing more. You have a bunch of blocks, a table mapping each block to its virtual location, and a couple convenience headers. If those count as a disk image when you put a filesystem inside, then I say a normal file is also a disk image when you put a filesystem inside. Especially because the sparse mapping is optional. For example, lots of VHDs are a raw file plus a 512 byte footer.
