Дима, а почему такое требование - tmpfs ?

мне вот уже давно более удобно в VM пробрасывать ramdisk нужного размера.
/dev/vdb                 4,0G         1,2G  2,7G           31% 
/home/rider/hasher

Как сделать так, что б оно собиралось у меня локально в моей 
конфигурации без использования tmpfs ?
