Se possível, configurar a montagem automática (autofs) seria a maneira padrão de fazer isso. Pode já estar na sua distribuição (vem com a instalação padrão do CentOS / Redhat). Aqui está um tutorial .
Por que usar o Automount?
Automounting is the process where mounting and unmounting of certain filesystems is done automatically by a daemon. If the filesystem is unmounted, and a user attempts to access it, it will be automatically (re)mounted. This is especially useful in large networked environments and for crossmounting filesystems between a few machines (especially ones which are not always online).
