Usually the pieces will end up in tmp/deploy/image/<machine>.
`obmc-phosphor-image-<machine>.*` are likely the rootfs pieces you're
looking for.  If everything has been built right you'll probably also
see initramfs, kernel, DTS, and u-boot blobs.

For the rootfs you'll likely see a squashfs-xz file, which is derived
from this:

```
classes/image_types_phosphor.bbclass:IMAGE_BASETYPE ?= "squashfs-xz"
```
