Sounds good. Well written and informative, with clear instructions. --- Alexander / xyproto

[2013-09-13 21:59:17 +0200] Pierre Schmitz: Anyway, we should still come up with a short news item; shouldn't hurt us and probably saves people some trouble. Here's a proposal: From version 207 on, systemd will not apply the settings from /etc/sysctl.conf anymore: it will only apply those from /etc/sysctl.d/* . Since the settings of our default /etc/sysctl.conf shipped by procps-ng have become kernel defaults anyway, we have decided to deprecate this file. Upon upgrading to procps-ng-3.3.8-3, you will be prompted to move any changes you made to /etc/sysctl.conf under /etc/sysctl.d . The easiest way to do this is to run: pacman -Syu mv /etc/sysctl.conf.pacsave /etc/sysctl.d/99-sysctl.conf If you never customized /etc/sysctl.conf, you have nothing to do. Also adding a line about the rationale of this upstream change would be nice. Anyone who knows feel free to add it to the proposal above. -- Gaetan
