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.
