Ok... subscribed to the list, and resending, because the list moderation seems to have eaten the attachment. > This patch is part of an upstream coordination, intended to unify the various ways distributions handle: - installation of kernels in the system - create the matching initrds; hooking up the various implementations of initramfs generators into the kernel package installation process - optionally/automatically create bootable rescue images to be able to recover from failures: https://fedoraproject.org/wiki/Features/DracutHostOnly All the above functionality is provided by the “kernel-install” tool: http://www.freedesktop.org/software/systemd/man/kernel-install.html It features: - flexible hookup/plugin directories to manage kernel installation and uninstallation. initrd, bootloader, rescue image management, all plug into that facility. - strict separation of distribution-supplied logic and local customization logic; system administrators are able to overwrite and replace/extend any part of the default logic if needed - hide distribution-specific logic behind a standardized command line interface - unify the custom kernel installation from the source tree with the usual kernel package installation; like the current /sbin/installkernel
