I meant for "name" to be the actual filename in the hashtable not the dev_t.
But yes, locators would be better. OTOH, for debugging and pretty printing,
it is still useful to have a device that prints the names. Finally a finay
format would be faster to read and it would not require parsing. So since
now it will not have strings, it is a lot easier to deal with and probably
the preferred method.
