[Bug 1750732] Re: grub package will change the boot order for MaaS deployed system

[Andres Rodriguez]

MAAS sends a debconf selection to curtin, so that curtin tells grub to
not update the nvram. The information that's required is:

1. The curtin config sent to curtin (maas <user> machine get-curtin-config <system_id>)
2. The installation log (you can grab both the UI/API)
3. The *actual* debconf selection set on the system (i guess you can query debconf to tell you what it is set to)
4. Please enable debug on debconf for the upgrade of grub to see what grub is doing with debconf.

** Changed in: maas (Ubuntu)
       Status: New => Incomplete

Title:
  grub package will change the boot order for MaaS deployed system

Status in curtin package in Ubuntu:
  New

Status in maas package in Ubuntu:
  Incomplete

Bug description:
  Similar to bug 1642298, this issue strikes back (looks like it's only
  affecting our node "lodygin - AMD Speedway Naples 2U" in the test
  pool)

  Steps:
   1. Deploy a system with Xenial
   2. Check the boot order with `efibootmgr`
   3. Upgrade grub-efi-amd64 from proposed
   4. Reboot
   5. Check the `efibootmgr` again

  Result:
   * The boot order will be overrided to boot from disk first, MaaS needs it to boot with PXE first.
