Automatically detect extra filesystems

[Justinzobel]

This should be relatively easy for most disks on Linux being /dev/nvme* /dev/sd*, etc

Maybe we can add an option to do this in the future.

However it won't work for Docker. You'd still need to explicitly mount the volumes to provide access.

Yeah, that's fine by me, I avoid Docker like the plague.
