[Bug 1328939] Re: Setting instance default_ephemeral_device in Ironic driver should be more intelligent
This wishlist bug has been open more than a year without any activity.
I'm going to move it to "Opinion / Wishlist", which is an easily-
obtainable queue of older requests that have come on. This bug can be
reopened (set back to "New") if someone decides to work on this.

Title:
Setting instance default_ephemeral_device in Ironic driver should be
more intelligent
Status in Ironic:

Bug description:
The instance default_ephemeral_device value needs to be set within the
nova driver to the partition where the ephemeral partition is created.
We currently hard code this value to /dev/sda1 to duplicate the old
nova-bm behavior. While this makes things work for TripleO [1], we
should do something smarter to determine the true partition value to
set (e.g., a Cirros image value should be /dev/vda1).
We could consider using something like udev by-label names (e.g.,
/dev/disk/by-label/NNN). This obviously adds a requirement on udev.
