[ Robert Millan ] * Backport from upstream: - Accept ZFS version 5000 (feature based).
[ Colin Watson ] * Silence error message on initial installation when /etc/default/grub does not yet exist. * Add GRUB_RECOVERY_TITLE option, to allow the controversial "recovery mode" text to be customised (LP: #1240360). * Backport from upstream: - Revamp hidden timeout handling by adding a new timeout_style environment variable and a corresponding GRUB_TIMEOUT_STYLE configuration key for grub-mkconfig. This controls hidden-timeout handling more simply than the previous arrangements, and pressing any hotkeys associated with menu entries during the hidden timeout will now boot the corresponding menu entry immediately (LP: #1178618). As part of merging this, radically simplify the mess that quick_boot.patch had made of /etc/grub.d/30_os-prober; if it finds other OSes it can now just set timeout_style=menu and make sure the timeout is non-zero. - Fix build with FreeType 2.5.1.
