Configure kernel parameters at boot via sysctl.d.

This stage creates a sysctl.d configuration file with the given name in /usr/lib/sysctl.d. Provided list of parameters is written as separate lines into the configuration file. At least one parameter must be specified. The syntax of the sysctl.d file is simply: <token> = <value> If a line begins with a single "-", any attempts to set the value that fail will be ignored. (from sysct.conf(5) man page) The <token> can be a glob pattern. A key may be explicitly excluded from being set by any matching glob patterns by specifying the key name prefixed with a "-" character and not followed by "=". (from sysctl.d(5) man page)
