systemd Status Update

Filed under
Software

It has been a while since my last status update on systemd. Here's another short, incomprehensive status update on what we worked on for systemd since then.

  • Fedora F15 (Rawhide) now includes a split up /etc/init.d/rc.sysinit (Bill Nottingham). This allows us to keep only a minimal compatibility set of shell scripts around, and boot otherwise a system without any shell scripts at all. In fact, shell scripts during early boot are only used in exceptional cases, i.e. when you enabled autoswapping (bad idea anyway), when a full SELinux relabel is necessary, during the first boot after initialization, if you have static kernel modules to load (which are not configured via the systemd-native way to do that), if you boot from a read-only NFS server, or when you rely on LVM/RAID/Multipath. If nothing of this applies to you can easily disable these parts of early boot and save several seconds on boot. How to do this I will describe in a later blog story.

  • We have a fully C coded shutdown logic that kills all remaining processes, unmounts all remaining file systems, detaches all loop devices and DM volumes and does that in the right way to ensure that all these things are properly teared down even if they depend on each other in arbitrary ways. This is not only considerably faster then the traditional shell hackery for this, but also a lot safer, since we try to unmount/remount the remaining file systems with a little bit of brains. This feature is available via systemctl --force poweroff to the administrator. The --force controls whether the usual shutdown of all services is run or whether this is skipped and we immediately shall enter this final C shutdown logic. Using --force hence is a much safer replacement for the old /sbin/reboot -f and does not leave dirty file systems behind. (Thanks to Fabiano Fidencio has his colleagues from ProFUSION for this).

  • Desk Changer is a Wallpaper Slideshow Extension for GNOME
    Have you been looking for a GNOME wallpaper slideshow extension? If so, you can stop. In the comments to our recent post on the way GNOME handles wallpapers a number of readers asked whether GNOME had an image slideshow feature built in, without the need for third-party apps and the like. The answer is yes, GNOME does. Sort of.
  • Minwaita: A Compact Version of Theme Adwaita for Gnome Desktop
    As you may already know that Ubuntu is switching back to Gnome, this is the transition time for Ubuntu to switch back. Some creators are motivated and creating themes for Gnome desktop, which is a good thing and hopefully we shall see plenty of Gnome themes and icons around soon. As its name shows "Minwaita" it is minimal/compact version of Adwaita theme, the theme is available after some enhancements to make Gnome more sleek and more vanilla Gnome experience without moving to away from Adwaita's design. This theme is compatible with Gnome 3.20 and up versions. This theme was released back in November, 2016 and still in continuous development that means if you find any problem or bug in the theme then report it to get it fixed in the next update. Obsidian-1 icons used in the following screenshots.
  • Gnome Pomodoro Timer Can Help You Increase Productivity
    If you are struggling with focus on something, it could be your work or study then try Pomodoro technique, this method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks. You can read more about Pomodoro here.
  • Widget hierarchies in GTK+ 4.0
    In GTK+3, only GtkContainer subclasses can have child widgets. This makes a lot of sense for “public” container children like we know them, e.g. GtkBox — i.e. the developer can add, remove and reorder child widgets arbitrarily and the container just does layout.
