Now that I know that initrd does contain NVMe drivers, I would ask whether my strategy for cloning is sensible. Firstly, here's my original partition table: =================================== $ sudo parted -l Model: ATA APPLE SSD SM0128 (scsi) Disk /dev/sda: 121GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 20.5kB 210MB 210MB fat32 EFI System Partition boot, esp 2 210MB 22.6GB 22.4GB hfs+ 3 22.6GB 23.2GB 650MB hfs+ 4 23.2GB 31.2GB 8000MB linux-swap(v1) swap 5 31.4GB 121GB 89.8GB ext4 linux =================================== Partition 3 is macOS, partition 5 is linux. I don't know why partition 2 is there, macOS's Disk Utility created it when I originally partitioned the disk to make room for linux. Partition 1 is the EFI partition, which is mounted on /boot/efi: =================================== $ df Filesystem 1K-blocks Used Available Use% Mounted on udev 4021656 0 4021656 0% /dev tmpfs 807236 1352 805884 1% /run /dev/sda5 85825416 68182636 13240004 84% / tmpfs 4036168 4892 4031276 1% /dev/shm tmpfs 5120 4 5116 1% /run/lock tmpfs 4036168 0 4036168 0% /sys/fs/cgroup /dev/sda1 201633 23678 177955 12% /boot/efi tmpfs 807232 0 807232 0% /run/user/113 tmpfs 807232 16 807216 1% /run/user/1000 =================================== The debian installer put the Grub2 loader in this partition: =================================== $ sudo ls /boot/efi/EFI/debian grubx64.efi $ sudo efibootmgr -v BootCurrent: 0000 Timeout: 5 seconds BootOrder: 0000,0080 Boot0000* debian HD(1,GPT,d43355a1-7dc2-4a96-ba68-4400a5db3981,0x28,0x64000)/File(\EFI\debian\grubx64.efi) Boot0080* PciRoot(0x0)/Pci(0x1c,0x5)/Pci(0x0,0x0)/Sata(0,0,0)/HD(3,GPT,911f18b9-6252-4cb8-8ad3-81c9ca73ded5,0x2a0f760,0x135f20)/File(\System\Library\CoreServices\boot.efi) Boot0081* Mac OS X PciRoot(0x0)/Pci(0x1c,0x5)/Pci(0x0,0x0)/Sata(0,0,0)/HD(3,GPT,911f18b9-6252-4cb8-8ad3-81c9ca73ded5,0x2a0f760,0x135f20) BootFFFF* PciRoot(0x0)/Pci(0x1c,0x5)/Pci(0x0,0x0)/Sata(0,0,0)/HD(3,GPT,911f18b9-6252-4cb8-8ad3-81c9ca73ded5,0x2a0f760,0x135f20)/File(\System\Library\CoreServices\boot.efi) =================================== Now, here is what I would perform: (1) Use macOS Time Machine to backup macOS on an external hard drive. (2) dd the linux partition into an image file: $ sudo dd bs=4M if=/dev/sda5 of=<ext_media>/debian_part.img (3) Install new drive. (4) Use macOS Recovery to restore macOS from the Time Machine backup. (5) I believe that point (4) will also restore the EFI partition, but will debian/grubx64.efi be preserved as well? Need to gather some info and check. Anyhow, I should have ended up with just two partitions: the EFI partition and the macOS partition. (6) Use macOS Disk Utility to partition the new disk. (7) How to restore the backed up debian partition? Do I need to reinstall a basic debian system from scratch and then run something like: sudo dd bs=4M if=<ext_media>/debian_part.img of=/dev/sdaN (where N is the new partition number)? Or is there some tool that can ease the recovery process? Thanks!
