No, that breaks due to the bug in debootstrap’s dependency “resolver” (see #557322, #668001, #768062) and the unwillingness of KiBi to fix that. That is, it breaks fresh installs. > 1) Heavily advertise (release-notes?) that doing an upgrade from > wheezy/etc to jessie will give you systemd as init system and inform > about the apt pinning solution.

Again: aborting the dist-upgrade in the debconf of one package may leave the system an ugly mess, especially if you don’t preconfigure packages. The linux-image-* check in their prerm for an attempt to remove the running kernel. Even that is borderline, and only somewhat acceptable because you would not normally do that during a dist-upgrade. This is not “suboptimal”, this invites not just new bugs but new classes of bugs. Recovering the system after that is going to be hell. One thing you *could* do is a debconf warning (just a message!) after the switch to systemd, to tell users to switch back manually *before* rebooting (for these cases where e.g. systemd is incompatible with the SoC’s 2.6 kernel you absolutely must run). Does that work, anyway (i.e. does installing systemd and immediately reverting to sysvinit leave the system net unchanged, modulo the dependencies it pulls in (see planet post))? > 3) Heavily advertise (again in release notes?) that you need to install > sysvinit-core and add the pinning file _before_ dist-upgrading.

Right, and I believe that a debconf *message* is appropriate, but a *prompt* with a choice to abort the upgrade is wrong. bye, //mirabilos -- Just a user… -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
