Note the proposal talks about adding support for ukis, not about removing support for current separate kernel+initrd setup. It surely is the goal to incrementally improve uki support to cover more use cases. I expect it will take quite some time to have ukis reach feature parity, and only then it makes sense to start thinking/discussing about eventually dropping support for non-uki kernels. Which may very well never happen, for starters switching existing installs automatically is a rather hard problem because the local generated initrd may have unknown customizations. > > A host-specific initrd / command line is needed today for: > [...] > > * configuration being specified on the kernel command line. > > ** root filesystem being the most important one. > > [https://systemd.io/DISCOVERABLE_PARTITIONS/ Discoverable partitions] > > allow to remove this. > > Why link to a page that only contains a link to another page?

Ok, looks like I should clarify that. I want fedora not depend on the kernel command line for configuration, so a unified kernel with the compiled-in default command line boots the system fine without needing any customization. If you want change the command line you surely can do that (assuming secure boot is disabled, otherwise systemd-stub ignores the command line). take care, Gerd _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
