Hi,
On aarch64 we are falling into the DS_MAYBE from [1] trap. While I do
not see any particular reason not to have a
aarch64) :;;
case to make this deterministic on aarch64 it does ultimately only work
as long as what we are doing sticks to those architectures.
As such I'd really like to get a better understanding why DS_MAYBE
exists. The way I see it it let's ds-identify kind of bail out and pass
the responsibility of identifying a data source to cloud-init by
enabling cloud-init.target.
And this is where we are tripping over because we check if cloud-init
got enabled and if it did we skip other stuff. But in this case we need
other stuff to happen.
So instead of checking on whether or not cloud-init got enabled would it
make more sense to check what is in /run/cloud-init/cloud-id?
If it contains "none" do our special stuff?
Thanks,
Robert
