xref: /OK3568_Linux_fs/buildroot/package/softether/0003-use-fhs-install-directories.patch (revision 4882a59341e53eb6f0b4789bf948001014eff981)

From b9420c3bfc2a8b9d35d0c8e5f6849007c2bc21fa Mon Sep 17 00:00:00 2001
From: Darik Horn <dajhorn@vanadac.com>

Subject: [PATCH] Use FHS installation directories.

Install to `/usr/sbin`, `/usr/lib`, and `/var/lib` according to the Linux
filesystem hierarchy standard if SoftEther is built through autotools.

In a managed installation, the FHS stipulates that the application must
accomodate a read-only installation path.  This requires a new `GetStateDir`
function that substitues `GetExeDir` in some parts of the code.
