I have a system which is a mishmash of testing and unstable and some from experimental.
How can I get a list of which packages I've installed from experimental?
Answering my own question.
I came up with this solution:
Then filter away packages which are not installed.
And keep only packages which are available in experimental.
If installed and upgradable version are the same we have a winner.
There might be an easy way to do that, but if there isn't this might work to get you close:
I hope for your sake there is a better way ;-)
