* Resynchronise with Debian. Remaining changes: - Automatically use existing EFI system partitions on Intel Macs as EFI boot partitions. - Create fat32 EFI partitions with the name "EFI System Partition" by default on Intel Macs. - choose_method/efi/do_option: Make sure no mountpoint is set. - Remove efi-modules dependency; it seems to be built into Ubuntu kernels now. - Require partman-base >= 129 to support a null value for the name. - Automatically mount the first method=efi filesystem we see on /boot/efi. - On x86 architectures, create EFI system partitions using FAT32 rather than FAT16, and require newly-created ones to have a minimum size of 34091008 bytes. - Never format EFI system partitions that already contain a filesystem. * Detect existing EFI system partitions more reliably on GPT partition tables (LP: #972122, #900245).
