systemd (247.2-2) unstable; urgency=medium systemd now defaults to the "unified" cgroup hierarchy (i.e. cgroupv2). This change reflects the fact that cgroupsv2 support has matured substantially in both systemd and in the kernel. All major container tools nowadays should support cgroupv2. If you run into problems with cgroupv2, you can switch back to the previous, hybrid setup by adding "systemd.unified_cgroup_hierarchy=false" to the kernel command line. You can read more about the benefits of cgroupv2 at https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html -- Michael Biebl Mon, 21 Dec 2020 18:40:10 +0100 systemd (247.2-1) unstable; urgency=medium KERNEL API INCOMPATIBILITY: Linux 4.14 introduced two new uevents "bind" and "unbind" to the Linux device model. When this kernel change was made, systemd-udevd was only minimally updated to handle and propagate these new event types. The introduction of these new uevents (which are typically generated for USB devices and devices needing a firmware upload before being functional) resulted in a number of issues which we so far didn't address. We hoped the kernel maintainers would themselves address these issues in some form, but that did not happen. To handle them properly, many (if not most) udev rules files shipped in various packages need updating, and so do many programs that monitor or enumerate devices with libudev or sd-device, or otherwise process uevents. Please note that this incompatibility is not fault of systemd or udev, but caused by an incompatible kernel change that happened back in Linux 4.14, but is becoming more and more visible as the new uevents are generated by more kernel drivers. To learn more about the required udev rules changes please check the "CHANGES WITH 247" section of /usr/share/doc/systemd/NEWS.gz. -- Balint Reczey Fri, 11 Dec 2020 18:22:42 +0100 systemd (236-1) unstable; urgency=medium DynamicUser=yes has been enabled for systemd-journal-upload.service and systemd-journal-gatewayd.service. This means we no longer need to statically allocate a systemd-journal-upload and systemd-journal-gateway user and you can now safely remove those system users along with their associated groups. -- Michael Biebl Sun, 17 Dec 2017 21:17:32 +0100 systemd (231-1) unstable; urgency=low This version drops support for running /etc/rcS.d SysV init scripts. These are prone to cause dependency loops, and almost all Debian packages with rcS scripts now ship a native systemd service. If you have custom or third-party rcS scripts you need to convert them or change them to run in rc2.d/ - rc5.d/; see this page for details: . -- Martin Pitt Thu, 14 Jul 2016 12:54:34 +0200 systemd (224-2) unstable; urgency=medium This version splits out systemd-nspawn, systemd-machined, and machinectl into the new "systemd-container" package. That now also enables systemd-importd. -- Martin Pitt Sat, 22 Aug 2015 15:58:43 +0200
