Not as far as I can tell; the idea just hadn't occurred to me. >> If the maintainers of systemd-the-package would be willing to not >> only split out these binaries into standalone package(s), but >> accept such init scripts for inclusion in those packages, > > Why would that be necessary? Which part? The splitting out, or the accepting of the init scripts? The splitting out I think I've already addressed, if not directly or at length; I can go over it more specifically if desired, although I sometimes have a hard time phrasing things in that context in ways which aren't unintentionally provocative. The short version would be: to avoid undesirable side effects from other parts of the systemd package. (Again, it's been long enough that I forget what those side effects were, although I think they had to do with logind.) The accepting of init scripts seemed to me like an essential piece of making sure those scripts would be present wherever they would be needed. Your suggestion above seems to provide a way to make it less essential, and thus would make moving forward easier and more practical. The only question is how to make sure that that other package would be present whenever a non-systemd init system is in use, and that seems like a simple matter of adding dependencies from the set-foo-as-active-init-system package for foo. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
