Motivated by Marcel's critique and suggestions.

I expected that it would be complicated and error-prone to allow
writing a .sources file during normal use of the image, such as a
user enabling or disabling a preference for caching the sources file.

Then I tried implementing it, so that I could show Marcel why this
would be a Really Bad Idea.

Conclusion: Marcel is right. Hopefully I captured his intent here :-)
