Hello pkg-sysvinit-devel Cc: seconds of the init system coupling GR Reading the latest replies on #765803 reveals that the ctte issue in that bug will probably not be resolved, and status quo will force all upgrades to systemd-sysv (in addition to new installations). It seems that the people opposing an automatic upgrade has to propose technical solutions to avoid this to happen, before the (now reduced) TC can make a decision. On way to solve this is to add a debconf prompt (unfortunately frowned upon) when upgrading from wheezy/testing as follows:
(for new installs the situation is different, with the installer choosing systemd-sysv by default, and you can only install sysvinit-core after the first reboot) Package: init Source: init-system-helpers Add a build dependency on debconf Script file: init-system-helpers.postinst + template file(s) One problem is that that package is maintained by the Debian Systemd Maintainers, so I cannot ask for help from them. 1) Detect if sysvinit-core is installed: If not: Issue a warning: You are about to switch init system, do you want that? yes) continue no) Install sysvinit-core (and if needed systemd-shim): Is that possible? Otherwise abort the upgrade and give a link to documentation (release notes??) about how to avoid switching init, including the pinning trick: create /etc/apt/preferences.d/no-systemd-sysv: Package: systemd-sysv Pin: release o=Debian Pin-Priority: -1 2) Detect if systemd-shim is installed: If not: (How to detect a desktop installation?) Issue a warning: You are about to install systemd components including systemd-sysv, i.e. changing init, do you want to do that? yes) continue no) install systemd-shim If the user wants a systemd-free desktop/server: creating /etc/apt/preferences.d/no-systemd: Package: systemd Pin: release o=Debian Pin-Priority: -1 (is this really sufficient to avoid any systemd package??, as systemd-must-die did) I've looked at the debconf tutorial, http://www.fifi.org/doc/debconf-doc/tutorial.html, but I'm not fluent in doing this and would appreciate help (If there is interest, otherwise we just give up??) Please forward this mail to anybody who might want to help. Time is short, 4th of December is the deadline. Thanks in advance! _______________________________________________ Pkg-sysvinit-devel mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-sysvinit-devel
