innostore and multi_backend

This:

{riak_kv,  [
    ....
    {multi_backend, [
         ....
         {<<"inno">>, riak_kv_innostore_backend, []}
     ]}
 ]},

....
 {innostore, [
         {data_home_dir, "/var/lib/riak/innostore"},
         {log_group_home_dir, "/var/lib/riak/inno-log"},
         {buffer_pool_size, 4294967296},
         {log_files_in_group, 6},
         {log_file_size, 16777216}
 ]}

Then this (without an entry for multi_backend, definitely won't work, since
it's not declared in multi_backend):
{riak_kv,  [
    ....
    {multi_backend, [
         ....
     ]}
 ]},

....
 {innostore, [
         {data_home_dir, "/var/lib/riak/innostore"},
         {log_group_home_dir, "/var/lib/riak/inno-log"},
         {buffer_pool_size, 4294967296},
         {log_files_in_group, 6},
         {log_file_size, 16777216}
 ]}


I also tried with {innostore, riak_kv_innostore_backend, []} in
multi_backend. First one gives the error mentioned in the previous email.
