When I create a fragmented table in Mnesia, all of the table fragments will have the suffix _fragN except for the first fragment. This is error-prone, since any code that accesses the table without specifying the correct access module will appear to work, since it reads from and writes to the first fragment, but it will not mix with code using the correct access module, since they will be looking for elements in different places.
Is there a way to tell Mnesia to use a fragment suffix for all table fragments? That would avoid that problem, by making incorrect accesses fail noisily.
For example, if I create a table with four fragments:
1> mnesia:start().
ok
2> mnesia:create_table(foo, [{frag_properties, [{node_pool, [node()]}, {n_fragments, 4}]}]).
{atomic,ok}
then mnesia:info/0 will list the fragments as foo, foo_frag2, foo_frag3 and foo_frag4:
3> mnesia:info().

I'd want foo to be foo_frag1 instead. Is that possible?
