sysctl.d/ file syntax with a "+" postfix?
In Redhat's documentation for making modifications to /etc/sysctl.d/
files, they have an specification:
<tunable class>.<tunable> = <value> +
<tunable class>.<tunable> = <value>
Note the trailing + on the first line. Is that, or has that ever been valid sysctl.d
file syntax? I have never seen it before and am just curious if that is a documentation error on their part or just something I have never run into before. If it is valid syntax, what does it do?
