Yes.  They'll be the same.  the bug was a result of metadata having
"ephemeral0" listed as "/dev/sda2" in an instance-store instance but as
"sda2" for a ebs instance. [1]

That said, the user can control this default behavior via cloud-config
now.  User data of the following will mount ephemeral0 on /opt:
 - [ ephemeral0, /opt ]

The same can also be specified in /etc/cloud/cloud.cfg in re-bundled

I think consistency makes sense.
