diskbuilder is an IncludeOS utility for creating raw FAT32 disk images. It is used in tests to generate FAT32 images for block devices and memdisk.

For testing diskbuilder, type nix-shell in the repository (requires Nix). The shell uses the Nix derivation in the repository root.

diskbuilder builds a FAT32 image from a specified directory, which serves as the root.

diskbuilder -o <output-image> <root-dir>

For verbose output, add the -v option before -o:

diskbuilder -v -o <output-image> <root-dir>
