In our usecases the separate partition is not needed. It is enough just
to put cloudinit configuration into the root filesystem.
This also allows to avoid a race condition which sometimes happens: some
process deletes the folder in tmp where the configuration partition is
mounted resulting in cloudinit failure to read its configuration.
