systemd-sysctl.service
SYSTEMD-SYSCTL.SERVICE(8) systemd-sysctl.service SYSTEMD-SYSCTL.SERVICE(8) NAME
systemd-sysctl.service, systemd-sysctl - Configure kernel parameters at boot SYNOPSIS
/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. EXAMPLES
Example 1. Reset all sysctl settings systemctl restart systemd-sysctl Example 2. View coredump handler configuration # sysctl kernel.core_pattern kernel.core_pattern = |/libexec/abrt-hook-ccpp %s %c %p %u %g %t %P %I Example 3. Update coredump handler configuration # /lib/systemd/systemd-sysctl --prefix kernel.core_pattern This searches all the directories listed in sysctl.d(5) for configuration files and writes /proc/sys/kernel/core_pattern. Example 4. Update coredump handler configuration according to a specific file # /lib/systemd/systemd-sysctl 50-coredump.conf This applies all the settings found in 50-coredump.conf. Either /etc/sysctl.d/50-coredump.conf, or /run/sysctl.d/50-coredump.conf, or /usr/lib/sysctl.d/50-coredump.conf will be used, in the order of preference. See sysctl(8) for various ways to directly apply sysctl settings. SEE ALSO
