The only problem I see, is that someone might forget to update /boot/grub/menu.lst (or lilo.conf) and set init=/sbin/upstart. I could use a debconf message and/or provide a README.Debian, but people are known to ignore such hints. This would mean, people would boot into a system with a mix of upstart's support binaries and init from sysvinit. As I want to avoid this potential problem, I think it's best, if upstart simply diverts all conflicting binaries from sysvinit. The only critical timespan will be between preinst and the upstart package being unpacked. This risk is acceptable to some extent, especially as you'd still be able to boot with init=/sbin/init.sysvinit, should the machine crash in between. So, with all the concerns raised so far, I'd propose the following: 1.) Remove "Conflicts/Replaces: sysvinit" from the upstart package. Divert all conflicting binaries from sysvinit and upload the package to experimental to give it some wider testing first. 2.) If no major problems are found, upload it to unstable after some time (weeks/months?). 3.) In the meantime work on a solution for the sysvinit-being-essential problem. Either by introducing a new essential package or through other means. This would happen after etch is released. 4.) Upload a version of upstart which removes the diversions again [*] and replaces sysvinit (meaning, sysvinit is uninstalled upon installation of upstart) Does that sound like an acceptable plan? Cheers, Michael [*] How can I get rid of a diversion again cleanly, without having to carry preinst around forever with something like: if dpkg --compare-versions $old_version lt $version_without_diversions; then remove_old_diversions fi -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
