+Subject: [PATCH] install: don't use ln --relative
+
+Oldish enterprise-class distributions have too old versions of
+coreutils, with ln not supporting --relative.
+
+So we fake it.
+
+ln --relative would create minimalist relative paths, but they are not
+trivial to generate. Instead, we always create paths relative to the
+root, i.e.:
+
+    ln -s --relative /usr/bin/foo /usr/sbin/foo
+
+would create:  /usr/sbin/foo -> ../bin/foo
+while we do :  /usr/sbin/foo -> ../../usr/bin/foo
