 Replying to [comment:1 igloo]:
 > Thanks for the report. In this case it's a feature;

 Although the point of the feature was to fail when trying to read from a
 non-existent package db. I don't think we considered the case of writing
 to a non-existent db. (Though I thought that did not work previously
 anyway, I thought dbs had to be initialised to contain "[]".)
