Any package relevant for successful boot. Any upgrade. As far as I can tell, the submitter requires some guarantees significantly stronger than what Debian requires for essential packages. In particular, boot-relevant packages are demanded to work in unconfigured state, with not fully satisfied dependencies (possibly not even unpackaged?), in partly unpackaged states, after maintainer script errors, and all of that in combination with system crashes that might result in partly written data to filesystems. And possibly in other interesting system states too. > (2) The TC is a decision-making body of last resort. The bug you > mention was filed today. Might this be premature? Well, if we close it or don't act on it, people will complain and/or demand to remove us from Debian for not acting on it (the latter might be limited to people just sitting on their porch). The other tech-ctte bug about usrmerge also suggested it would just end up here either way. Ansgar
