Thank you! No problem thank you for the review.

- Priority is now optional
- Architecture is now arm64
- I had no reason for the multi-user.target and basic is even better, in situation where the device would boot from a very very slow usb drive and take more more than 10min to boot. So I changed it.

Assuming this first review is coming to an end, I will find a second
reviewer to keep the race against time going :)

Title:
  [needs-packaging] dgx-desktop-sbsa-gwdt-loader

Status in Ubuntu:
  New

Bug description:
  Git URL: git.launchpad.net/~antoinelassagne/+git/dgx-desktop-sbsa-gwdt-loader
  Upload: https://launchpad.net/~antoinelassagne/+archive/ubuntu/cypress/+packages?field.name_filter=dgx-desktop-sbsa-gwdt-loader&field.status_filter=published&field.series_filter=

  This package selectively load the sbsa_gwdt watchdog, which is
  necessary with certain platforms but blacklisted by default per kernel
  policy
  (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1432837/comments/6).
  Without it, The Nvidia DGX Spark will reboot after 10 min of uptime,
  all the time.

  However blacklisted kernel modules can still be loaded with modprobe.
  This is a service that takes the modalias, looks for
  "NVIDIA_DGX_SPARK" into it, and modprobes the watchdog if it finds it.
