* 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.
