Owner

• Name: LennartPoettering

Current status

• Targeted release: Fedora 14
• Last updated: 2010-07-01
• Percentage of completion: 10%

Benefit to Fedora

Fedora currently uses Upstart but in SysV compatibility mode. systemd is a overall better design as detailed in http://0pointer.de/blog/projects/systemd.html.

Scope

Requires building packages for systemd, and taking advantage of it in a dozen or so desktop daemons that will benefit from systemd the most at present and make it default for Fedora 14.

Test Plan

1. Boot the system, make sure all services come up. 1. Move between runlevels, ensure the proper starts and stops take place. 1. Check the various admin tools such as /sbin/service, system-config-services, chkconfig, etc.

User Experience

The user should notice considerably faster bootup.

Dependencies

• Successful Fedora Package review and addition to rawhide
• http://www.freedesktop.org/wiki/Software/systemd

Contingency Plan

• Continue to ship the current SysVinit package

Documentation

• Instead of bash scripts, systemd uses dot service files, currently located in /usr/share/systemd/system/ (This needs to move into /etc)
• http://www.freedesktop.org/wiki/Software/systemd

Release Notes

Fedora 14 has replaced Upstart with systemd. systemd uses services files located in path/to/files. A dozen desktop daemons [list them] have been initially converted to use systemd service files and small number of programs have been patched to take advantage of it. systemd is compatible with legacy SysV init scripts and rest of the migration will happen incrementally over time.
