Thanks, yes, that's what it looks like.  I don't think it is reliable
though, as it depends on the discovery order, which is not
predictable.  See commend in olpc-sd.rules in dracut-modules-olpc.

Looking at olpc-boot-cmdline.sh in dracut-modules-olpc, we use
/dev/disk/mmc references instead of the legacy /dev/mmcblk references.
