No, I meant someone who starts out installing our OS. How do they know the gpg key that they get is the real valid one? Right now, they use... a well known ssl cert to download the OS over https. Just like the metalinks that they would download later. > > So rpm-md repo signatures are desirable. (And same for > the ostree repo side) Well, it changes it from having to use a ssl cert once (to download the initial OS) to using it all the time (downloading metalinks/updates), which I suppose reduces the ssl cert issue, but does not get rid of it. kevin
