systemd/upgrade

Note
This article currently (2021) contains only instructions for updates that were required years ago, and should no longer be needed. If a more involved upgrade (that requires instructions) happens again, it should be accompanied by a corresponding news item (that should be read and followed), and may also get a new entry here.

This page only lists changes, which must be considered before updating Systemd or risk system brakege. For regular updates, see sys-apps/systemd's changelog or upstream's NEWS file.

systemd 203

The compatibility symlinks /bin/systemctl and /bin/systemd pointing to /usr/lib/systemd/systemd are deprecated. The ebuild checks whether the system was booted using compatibility symlinks and refuses to build the new version of systemd.

To upgrade systemd, update the bootloader to use init=/usr/lib/systemd/systemd and reboot the system.

systemd 200

See the udev upgrade article.

systemd 187

graphical.target now depends on the display-manager.service for starting a display manager like GDM, KDM, etc. . Create a new .service file, e.g. for KDM:

FILE /etc/systemd/system/kdm.service

[Unit]
Description=KDM Display Manager
Conflicts=getty@tty1.service
After=systemd-user-sessions.service getty@tty1.service plymouth-quit.service

[Service]
ExecStart=/usr/bin/kdm -nodaemon
Restart=always
IgnoreSIGPIPE=no

[Install]
Alias=display-manager.service

Now enable the new service, e.g. for KDM:

root #systemctl enable kdm.service

Afterwards starting KDM with systemd >=187 should work. Disable and delete the old .service file (e.g. kdm@.service).

For the rationale and more informations see the Fedora 18 feature "Display Manager Infrastructure Rework".
