If I change the

osProfile

of a

ScaleSet

I get this outputted from `pulumi up`:

azure:compute:ScaleSet  azureDemo-ss2             updated     [diff: ~osProfile]

However, the actual instances are not restarted. When changing

customData

, I would expect instances to restart to apply the new customData.

This appears to be intended behaviour of the Azure Terraform provider. I am honestly not sure why that is. If you also change the

computerNamePrefix

, that will trigger a replacement - which could be a workaround here.

Right - the behavior doesn't make sense to me either.
