| Subject: [PATCH] init.d/sysctl.in: add support for busybox sysctl |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| Busybox version of sysctl does not support --system argument, |
| and files need to be loaded one by one. This patch adds code |
| to recognize busybox sysctl and execute proper function based |
| on that. |
