it was used via /etc/init.d/boot.sysctl: /sbin/sysctl -e -q --system
but sysctl isn't used anymore, systemd-sysctl is now, and I'm not sure it is worth adding support for this (currently, it will follow what is descripted in man sysctld). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I noticed that /etc/sysctl.conf was not being read starting with systemd version 195 (default openSUSE 12.3). Until now, the changes I was running in /etc/sysctl.conf were optional but today I have encountered a CRITICAL problem created by this bug... Without getting in detail (I'll be opening a separate bug), libvirt is configuring virtual network forwarding where it's not being read by systemd. The general solution is to edit /etc/sysconf if there is a problem and of course now that advice is invalid. Unfortunately, the MAN pages for systemd-sysconf.service are inadequate. They point to locations this new Unit reads, but they are empty and don't provide templates or guidance how to format. So, in other words there is now some urgency as systemd is removing and replacing subsystems, either backwards compatibility for /etc/sysctl.conf needs to be implemented (the topic of this bug) or the appropriate MAN pages improved or templates provided (probably for some other topic).

Hello all, As resolving this issue is discussed, is there a recommended workaround today?
I noticed that /etc/sysctl.conf was not being read starting with systemd version 195 (default openSUSE 12.3). Until now, the changes I was running in /etc/sysctl.conf were optional but today I have encountered a CRITICAL problem created by this bug...
I think you are confusing things. /etc/sysctl.conf is read and applied by systemd-sysctl This bug is about /boot/sysctl.conf-* -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This bug got me curious, I have a number of kernels loaded on my machine at the moment (3.9x, 3.8x, 3.7.10x) and when I inspect the /boot/syxctl.conf-* files they all contain the exact same parameters. So although I can understand being cautious, at least on my machine they're all the same. Would be interesting if it's common to write kernel-specific parameters or if it's not current practice. Some Googling suggests that the OP's example actually can be implemented without problem in the more(?) commonly configured /etc/sysctl.conf which should be read by systemd-sysctl.service (which isn't on my machine, but that's another issue). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In an ideal world, we'd be able to ship just one kernel and the flavors would just load the different sysctl.conf files for the desired behavior. That goal is a long way off, though. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
