* Creating a file nix-support/no-scan in the output path of a
derivation disables scanning for dependencies. Use at your own risk. This is a quick hack to speed up UML image generation (image are very big, say 1 GB). It would be better if the scanner were faster, and didn't read the whole file into memory.
