  I'm not sure whether devtmpfs handles device node removal itself.
I'd need to test that.

  In any case, the answer to your original question is no, you cannot
configure mdev to run but not remove nodes. You can patch it, though:
the relevant part of the code, which you may want to comment, is the
following block:

                 if (operation == OP_remove && major >= -1) {
                         if (ENABLE_FEATURE_MDEV_RENAME && alias) {
                                 if (aliaslink == '>') {
                                         dbg1("unlink: %s", device_name);
                                         unlink(device_name);
                                 }
                         }
                         dbg1("unlink: %s", node_name);
                         unlink(node_name);
                 }
