+Subject: [PATCH] fix version extraction when building in a larger git tree
+
+sslh uses host git to extract its own version number. In buildroot, this
+is an issue since extracted information is conflicting with buildroot git
+status if we use git as VCS for buildroot.
+
+Since these git calls are legitimate only if git is used for the sslh
+subtree only, this patch adds a check : a .git directory has to exist at
+the root of the project to enable git-extracted version string.
