I solved issue locally by direct patching the GRASS plugin:

+    // GIS.lab hacks
+    environment.insert( "TMPDIR", "/mnt/booster" );
+    environment.insert( "GRASS_VECTOR_TEMPORARY", "move" );
+    environment.insert( "GRASS_VECTOR_TMPDIR_MAPSET", "0" );
+
     if ( mDirect )
     {
       QStringList variables;
diff --git a/src/plugins/grass/qgsgrassshell.cpp
b/src/plugins/grass/qgsgrassshell.cpp
index adedbcb..8e51634 100644

+  env << "GRASS_VECTOR_TEMPORARY=move";
+  env << "GRASS_VECTOR_TMPDIR_MAPSET=0";

GRASS plugin should read environmental variables from
$HOME/.grass7/bashrc or %APPDIR%/GRASS7/env.bat.
