Hi everyone, systemd 231 was built for rawhide / F25 today, with a bunch of usability and security features, see [1]. Please give it a test. There have been various discussion about reducing the footprint of systemd, this release and the previous one make some progress: 1. Code shared between various systemd binaries is now installed as a private shared library (/usr/lib/systemd/systemd-shared-231.so) with unstable API and ABI. This gives a nice reduction: 18.7 → 8.4 MiB reduction in installed size for the main systemd rpm between systemd 229 and 231. Incidentally, the patches for this were provided by Debian and Ubuntu maintainers, so this is a nice example of cross-distro cooperation. 2. The dependency on libxkbcommon has been reduced from Requires to Recommends, and the .so is dlopen'ed at runtime if available. libxkbcommon is <300 kiB, but it pulls in xkeyboard-config, which is 5.3 MiB. 3. Upstream added %systemd_ordering macro to be used as relaxed version of %systemd_requires [2]. Doing that replaces Requires rpm dependencies with OrderWithRequires dependencies, allowing a package to be installed into a minimal image with no systemd, while still allowing presets to be correctly executed when installed (as part of the same transaction) *with* systemd. In Fedora, this still needs to go through FPC [3], and of course individual packages need to be modified. This is only possible for daemons which make no use of other systemd services (like tmpfiles) and can be started through some other mechanism, so no automatic conversion is possible. Together with the split into systemd / systemd-container / systemd-udev / systemd-journal-remote which was implemented for F24, we are making good progress ;) [1] https://lists.freedesktop.org/archives/systemd-devel/2016-July/037220.html [2] https://bugzilla.redhat.com/show_bug.cgi?id=1118740 [3] https://fedorahosted.org/fpc/ticket/644 Zbyszek -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
