or a zealous recipe. That is his responsability, and backups are
done for that.
I don't think backups are the right approach. It's a mistake to
have recipes manage precious data. If you really really really
think that's a good idea, then the recipe should at least manage
uninstall and move precious data aside, rather than remove it.
I don't think it is really the user's problem is a recipe
misbehaves by allowing precious data to be removed.
I'll note fassembler uses a file abstraction layer so that its
recipes are safe by default: https://svn.openplans.org/svn/fassembler/trunk/fassembler/filemaker.py
I think buildout would be a lot more humane if it took the same
approach.
I'd be interested to know what you mean by this, but I'm not willing
to read that source to find out.
Can you be a little more specific?
