I installed 0install on a new (Windows) machine. On the previous one, I had a bunch of feeds I packaged using the GUI tools into a catalog. I publish the catalog and registered it at http://roscidus.com/0mirror/. When I tried creating a new app on the new machine, it looks like 0install automatically created a new gpg key (?) and used it for signing (or am I misunderstanding something?). I tried to search for some info in the docs about private gpg keys storage, but wasn't successful in finding any.
Is there some way to carry my private gpg signing keys with me from one machine to another? Is it documented in the docs somewhere that I failed to find?
