sysctl.d — Configure kernel parameters at boot
/etc/sysctl.d/*.conf
systemd uses
/etc/sysctl.d/
to configure
sysctl(8)
kernel parameters to load during boot. Each
configuration file is named in the style of
/etc/sysctl.d/<program>.conf
.
The configuration files should simply contain a list of variable assignments, separated by newlines. Empty lines and lines whose first non-whitespace character is # or ; are ignored.
Note that both / and . are accepted as separators in sysctl variable names.
