Please don't misunderstand me on this. I am explicitly *not* criticizing the kernel people for not wanting to give hibernation their love. I don't expect them to, and as an upstream maintainer I know exactly how important it is to make choices on what you want and what you don't want to support. Hence: it's entirely fine by me if hibernation is considered not supportable. I am just saying given that things are the way they are I think it would be better to not advertise it to userspace as working. Because currently to the layers further up in the stack it looks like hibernation was perfectly well supported even though it apparently is not. > > To compare this with other cases: usually code that the package > > maintainers don't want to maintain with the highest priority and > > greatest love is split into separate RPMs, and not installed by > > default.

Yes, precisely, and the suggestion is to turn it off hence in the kernel in a way that allows people who understand the uncertainty around this subsystem to then enable it anyway if they like. i.e. make this subsystem opt-in instead of opt-out, in the package that actually implements the subsystem (i.e. the kernel rpm), and under control of the people who made the decision not to support it with all their love (i.e. the kernel team). I don't think systemd should be in the business of second-guessing the kernel team's choices on code quality and their desire to support code. Because if the kernel doesn't turn this subsystem off, then we have to… Lennart -- Lennart Poettering, Red Hat _______________________________________________ desktop mailing list -- desktop@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to desktop-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/desktop@xxxxxxxxxxxxxxxxxxxxxxx
