My personal kernel system variables configuration for web servers.
Files found under the
/etc/sysctl.ddirectory that end with
.confare parsed within sysctl(8) at boot time. If you want to set kernel variables you can either edit
/etc/sysctl.confor make a new file.
The filename isn't important, but don't make it a package name as it may clash with something the package builder needs later. It must end with
My personal preference would be for local system settings to go into— `/etc/sysctl.d/README.sysctl`
/etc/sysctl.d/local.confbut as long as you follow the rules for the names of the file, anything will work. See sysctl.conf(8) man page for details of the format.
