Off the top of my head, perhaps create some sort of scriptlet (probably to live in initscripts, since that's what owned prefdm) to parse /etc/sysconfig/desktop to make some educated guess about which dm service to enable. nucleo mentioned to me on irc the case also of the simple case of a machine with no DM. If the expactation that yum install gdm (or any DM, with no DM currently enabled) should 'just work', then perhaps also consider doing something like this in gdm's %post scriptlet: systemctl is-enabled display-manager.service || \ systemctl enable gdm.service ok, ignore this, looks like presets are the way to go here. -- rex -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

(or is this case already handled somehow?) This should be handled already bei the postinst scriptlet in the systemd RPM. I must admit though that I gave that bit only minimal testing. But it should work, and the core of it is just copied out of the old prefdm script, so that we closely convert the old settings into new settings. Off the top of my head, perhaps create some sort of scriptlet (probably to live in initscripts, since that's what owned prefdm) to parse /etc/sysconfig/desktop to make some educated guess about which dm service to enable. That's pretty much exactly what we have, except that this actually resides in systemd.rpm.

(Optionally) Patch systemd to parse /etc/sysconfig/desktop at upgrade time and generate a symlink from it that is stored in /etc/systemd/system/display-manager.service and ensures that the original display manager choice is kept. I have DISPLAYMANAGER=KDE in /etc/sysconfig/desktop but symlink was not generated after Rawhide update. Hmm, that would suggest that this bit is borked: http://pkgs.fedoraproject.org/cgit/systemd.git/tree/systemd.spec#n300 If you execute that by hand in a shell, does it work for you then?

Lennart This part of code creates symlink (after installing all updates including systemd and kde-settings-kdm). But as I commented in bug 847472, symlink also created after updating systemd if kde-settings-kdm was previously updated to version which adds kdm.servise. If systemd and kde-settings both updated at once then symlink not created. https://bugzilla.redhat.com/show_bug.cgi?id=847472#c5 -- Alexey Kurov nuc...@fedoraproject.org -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
