Unfortunatelly, autofs doesn't allow to discover it's type. At least without
accessing master process. That means, that stat can be used to determine
whether some other file system is mounted on top of autofs (which we need to
take a decision whether to move restore fs aside or not), because it simply
stuck.
This patch does fs type discovering by parsing CTs mountinfo.
