Comment # 12 on bug 904544 from Leonardo Chiquitto

After this patch, function check_sysctl() looks like this:

> function check_sysctl () {
>     local output_file=`mktemp -t check_sysctl.XXXX` # TEMPDIR is set but not exported.. does it work?
>     /usr/sbin/sysctl -a > "$SEC_DATA/sysctl.new"
>     cat "$SEC_DATA/sysctl.new"
>     mv "$SEC_DATA/sysctl.new" "$SEC_DATA/sysctl"
> }

The (now unused) $output_file is created but never removed
