To be honest, I've ignored the "every MB >> counts" aspect entirely for now.

That's the point, we want a reasonably small package while still providing the required functionality. Not sure how providing a fixed size number is helping in this. But most of all, I didn't throw in a number because I have no idea what is reasonably possible. I really only just said "every MB counts" because the question came up before (in Josh's old thread) and I hoped I could stop this discussion from happening again before we have any numbers for this. > Of course. :-) > >> >> FWIW, the existing kernel package installed today (a debug kernel >> even) is ~142 MB. 123MB of that is the /lib/modules content. ~6MB of >> that is vmlinuz.

Well, if we can remember why we put up a fixed size requirement, why can't we remember why we did the chopping? ;) Anyway, I think it's fair to define a "kernel-core should be smaller than X MB" requirement but I don't think it's fair to say Y MB because I like the number Y. I also don't like that we might throw out e.g. NFS just because we're 1MB over the limit. But if it helps the kernel team to have a fixed number, someone tell me what we roughly save by throwing out the stuff we discussed and we can discuss what number would long-termish make sense, I guess. Also, I'm not sure whether we should measure the extracted files, the compressed RPM or both. -- Sandro _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
