Meanwhile, /usr/lib/systemd/systemd-sysctl as used during boot, keeps working fine (i.e. changes to /etc/sysctl.conf become active on next boot) -- You are receiving this mail because: You are on the CC list for the bug.

But your hint that systemd works, is not useful for me. I need to change the setting also after the boot - with the "right" tool. Of course I know the echo X > /proc/sys/... method as a workaround at the moment. systemd-sysctl is no real replacement for sysctl. -- You are receiving this mail because: You are on the CC list for the bug.

But your hint that systemd works, is not useful for me. I need to change the setting also after the boot - with the "right" tool.
Sure! I did not want to imply systemd-sysctl would be a suitable replacement. Just meant that as an observation about what still works. I also use "sysctl -p" in various places, e.g. rpm package POST scripts, to get freshly installed /etc/sysctl.d snippets activated. And all that fails now. I notice that even the openSUSE base system does that, e.g. the firewalld package contains a /etc/modprobe.d/firewalld-sysctls.conf calling out to /sbin/sysctl, which will be broken now, too. -- You are receiving this mail because: You are on the CC list for the bug.
