I have no opinion on delta packages except that they scare me and sound like a very easy way to screw things up horribly. What I'm interested in is package deltas -- given foo-1.0.0.txz and foo-1.0.0-to-1.0.1.bsdiff, generate foo-1.0.1.txz. In other words, a way to speed up "download new packages", not a change to the upgrade process (since having generated the new package, you would still be uninstalling the old package and installing the new one). -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
