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
