But could we connect the term "eipp.log" and its documentation *somewhere*? You remember we recently talked about that in #debian-apt and back then I was just as confused as Marc is right now what /var/log/apt/eipp.log.xz is about. This doesn't mean that external-installation-planner-protocol.md has to point to eipp.log.xz if you say that this file should just document the format. But somewhere in the docs there should be a find-able connection between /var/log/apt/eipp.log.xz and external-installation-planner-protocol.md. > > > What do you think is missing?

Thanks, this is great to know! > All the concerns raised here also apply to edsp, and well any log file. Yes, fixing those would be awesome as well. :) Thanks! cheers, josch
