That could be done, if it solves this problem. Damn, now we have the
naming problem back again. :)

By doing its own fstype, we could also make the auto-mount optional,
because you could always reach the filesystem anytime later.

A different fstype has the slight inconvenience, that existing
userspace needs to be taught to handle it explicitly, while a tmfps is
already handled automatically because we use tmpfs already today. But
that may not be too important.

Thanks a lot for your tests and analysis,
Kay
