NAME¶
systemd-sysctl.service, systemd-sysctl - Configure kernel parameters at bootSYNOPSIS¶
/lib/systemd/systemd-sysctl [OPTIONS...]
[CONFIGFILE...]
systemd-sysctl.service
DESCRIPTION¶
systemd-sysctl.service is an early boot service that configures sysctl(8) kernel parameters by invoking /lib/systemd/systemd-sysctl. When invoked with no arguments, /lib/systemd/systemd-sysctl applies all directives from configuration files listed in sysctl.d(5). If one or more filenames are passed on the command line, only the directives in these files are applied. In addition, --prefix= option may be used to limit which sysctl settings are applied. See sysctl.d(5) for information about the configuration of sysctl settings. After sysctl configuration is changed on disk, it must be written to the files in /proc/sys before it takes effect. It is possible to update specific settings, or simply to reload all configuration, see Examples below.OPTIONS¶
--prefix=Only apply rules with the specified prefix.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
