+  * Drop use of --removable flag to grub-install from
+    live-build/buildd/hooks/02-disk-image-uefi.binary, to match the cloud
+    images (7c760864fdcb278ca37396f06f5e3f297428d63d).  This fixes
+    bootloader updates in the buildd images, but also fixes compatibility
+    with using devtmpfs for losetup.
