Merge ~juliank/grub/+git/ubuntu:ubuntu into ~ubuntu-core-dev/grub/+git/ubuntu:ubuntu

[Julian Andres Klode]

[Julian Andres Klode (juliank)]

It's not clear to me why git-dpm removed the patches it removed, but it seems they're not in the series file anyway?

[Julian Andres Klode (juliank)]

Ah I see, I should move the patches to debian/gettext-patches or something so that git-dpm does not override them. But that's for elsewhere :)

[Dimitri John Ledkov (xnox)]

Please revert/resurrect gettext patches.

[Dimitri John Ledkov (xnox)]

TODO test that latest entry points at the right kernel flavour in normal & zfs boots.

[Julian Andres Klode (juliank)]

Updated:

- moved the ZFS changes into the original ZFS patch
- fix unset variable errror if GRUB_FLAVOUR_ORDER is undefined
- Add version_test_gt to {a,b}_preferred variable names for scoping purposes

Still need to move the gettext bases in the base branch and rebase on that so they get preserved.

[Julian Andres Klode (juliank)]

Merged patch for bug 1878541

[Dimitri John Ledkov (xnox)]

Everything looks good.

Note to self: zfs script does not have multi-initrd support.

review: Approve

 grub2 (2.04-1ubuntu27) UNRELEASED; urgency=medium
 
   * Move gettext patches out of git-dpm's way, so it does not delete them
+  * debian/patches/ubuntu-flavour-order.patch:
+    - Add a (hidden) GRUB_FLAVOUR_ORDER setting that can mark certain kernel
+      flavours as preferred, and specify an order between those preferred
+      flavours (LP: #1882663)
+  * debian/patches/ubuntu-zfs-enhance-support.patch:
+    - Use version_find_latest for ordering kernels, so it also supports
+      the GRUB_FLAVOUR_ORDER setting.
+  * debian/patches/ubuntu-dont-verify-loopback-images.patch:
+    - disk/loopback: Don't verify loopback images (LP: #1878541),
+      Thanks to Chris Coulson for the patch

+Subject: UBUNTU: disk/loopback: Don't verify loopback images
+
+When a file is verified, the entire contents of the verified file are
+loaded in to memory and retained until the file handle is closed. A
+consequence of this is that opening a loopback image can incur a
+significant memory cost.
+
+As loopback devices are just another disk implementation, don't treat
+loopback images any differently to physical disk images, and skip
+verification of them. Files opened from the filesystem within a loopback
+image will still be passed to verifier modules where required.

+This allows you to specify flavours that will be preferred

+- items in the list win over items not in the list, and items
+earlier in the list win over later ones.
+
+We still have to sort out storage of this, as we need to
+inject that from packages or the UA client and similar,
