Hi all. I've been suggested to report this problem here. First reported in the arch linux forums: https://bbs.archlinux.org/viewtopic.php?id=170005 It seems systctl assumes by default that the /etc/sysctl.conf file exists. In arch linux after the upgrade to systemd 207 this file no longer exists and will not be read even if created by hand (instead /etc/sysctl.d/99-sysctl.conf is suggested if any change from the default values is needed). At least when running "sysctl -p" or "sysctl --system", the commands fail because they assume that /etc/sysctl.conf exists, and exit with an error when it is not found. Could sysctl use the conf files in /etc/sysctl.d/ as a fallback if /etc/sysctl.conf doesn't exist? ----------- I'd flash you my business card, but my hands are too full of guns. - Peter Quill, aka Star-Lord, making another dashing rescue
