But I have closed the issue (without really trying the methods) because Tobias writes: > But we can go deeper if we choose to, by dropping zisofs and going for > something like squashfs, which achieves higher compression through > higher block sizes and better algorithms like XZ. Probably yes, though I don=E2=80=99t dare writing that and Csepp writes: > Are there unnecessary dependencies that could be cut out? Kind of, but only by making variant packages without the dependencies that Maxime listed in his response, just for the installer, but it would not be enough to get below 700MB. Maxime writes: > I think -Os would be worth investigating. Yes, that would be easiest, though looking at --tune, I guess making variant base packages with -Os just for the installer is not worth the complexity since cdroms are a niche use-case. It would be possible, so maybe I shouldn=E2=80=99t have closed, but maybe I shouldn=E2=80=99t have filed the issue in the first place. Regards, Florian
