After reading sysctl-related manpages in systemd, I started to wonder about the logic behind /etc/sysctl.conf shipped with core/procps-ng. If one follows systemd's conventions, this file should be in /usr/lib/sysctl.d and mnemonically called something like "100-archlinux-default.conf". Also note, that systemd currently doesn't document /etc/sysctl.conf at all...

See: /usr/lib/systemd/system/systemd-sysctl.service

This is the legacy location of the kernel parameters configuration file. Eventually I would like to get most things out of it and to /usr/lib/... In the meantime it's fine as it is; if you have any specific issues or want a parameter to be taken out to /usr/lib please open a feature request.

Thanks for the explanation. Yes, I know that systemd parses the legacy sysctl.conf and I don't have any issues with the default (4 uncommented) sysctl parameters, although I do change most of them :)

But after moving my configuration into /etc/sysctl.d/, I found it odd to keep an empty sysctl.conf to "mask" the defaults (I don't know whether /etc/sysctl.d has a higher preference than sysctl.conf in the current systemd) instead of doing it via symlinks in /etc/sysctl.d/. It seems logical and alignes with systemd documentation to have distro-specific settings in a fixed-name .conf file inside /usr/lib/sysctl.d/...

Cheers.

Best,
