Re: [Merge] ~chad.smith/cloud-init:bug/1840080-ubuntu-drivers-emit-latelink-v2 into cloud-init:master


Just validated on Eoan that this package properly sets up linux/nvidia/latelink true via debconf-get-selections.

The ubuntu-drivers-common package fixes has not yet published to Eoan. So, end-to-end validation will not be possible until an updated ubuntu-drivers-common and linux-modules-nvidia* is published.

As it is, this behavior paves the way for the ubuntu-drivers-common/linux-modules-nvidia package features.

# cloud-init properly registers and sets linux/nvidia/latelink : true
