Virgil Dupras 2ae84fcc51 Revert tmpfs mount removal
To fix #406, I reverted the tmpfs mount we add at boot time. As we can
see in #455, it was a bad idea.

In addition to bringing back that mount, I've also added a
`tmpfs_mount_size` config that allows to change the size of the mount
from its default `2G`. It's also possible to disable the mount
altogether.

fixes #455
