[Chad Smith (chad.smith)]

On this Xenial branch we probably should add the following to debian/changelog

   * debian/control: drop Build-Depends on linting tools, they haven't been
   * debian/*: drop python-curtin, making the package Python 3-only.
   * debian/rules get in sync with 0.1.0~bzr470-0ubuntu1 [Paride Legovini]

I saw these lines automatically added to my debian/changelog due to a `new-upstream-snapshot 20.2`

review: Needs Fixing

[Chad Smith (chad.smith)]

Oops take back that comment as you mentioned in MM. These commits were forward-ported to master, so we don't need to catalog them here.

 value is 'unmodified' then Curtin will not set any value at all and will
 use Grub defaults.
 
+**reorder_uefi**: *<boolean: default True>*
+
+Curtin is typically used with MAAS where the systems are configured to boot
+from the network leaving MAAS in control.  On UEFI systems, after installing
+a bootloader the systems BootOrder may be updated to boot from the new entry.
+This breaks MAAS control over the system as all subsequent reboots of the node
+will no longer boot over the network.  Therefore, if ``reorder_uefi`` is True
+curtin will modify the UEFI BootOrder settings to place the currently booted
+entry (BootCurrent) to the first option after installing the new target OS into
+the UEFI boot menu.  The result is that the system will boot from the same
+device that it booted to run curtin; for MAAS this will be a network device.
+
+On some UEFI systems the BootCurrent entry may not be present.  This can
+cause a system to not boot to the same device that it was previously booting.
+If BootCurrent is not present, curtin will update the BootOrder such that
+all Network related entries are placed before the newly installed boot entry and
+all other entries are placed at the end.  This enables the system to network
+boot first and on failure will boot the most recently installed entry.
+
+This setting is ignored if *update_nvram* is False.
+
+**reorder_uefi_force_fallback**: *<boolean: default False>*
+
+The fallback reodering mechanism is only active if BootCurrent is not present
+in the efibootmgr output.  The fallback reordering method may be enabled
+even if BootCurrent is present if *reorder_uefi_force_fallback* is True.
+
+This setting is ignored if *update_nvram* or *reorder_uefi* are False.
+
+**remove_duplicate_entries**: <*boolean: default True>*
+
+When curtin updates UEFI NVRAM it will remove duplicate entries that are
+present in the UEFI menu.  If you do not wish for curtin to remove duplicate
+entries setting *remove_duplicate_entries* to False.
+
+This setting is ignored if *update_nvram* is False.
