2 - Partition Layout

The bootable Leda Quickstart images are disk image with multiple partitions:

  • Two bootloader partitions, to enable A/B update process
  • A separate partition to hold bootloader status information
  • An optional rescue partition with basic operating system and tooling
  • Two rootfs partitions with a full installation of the operating system, to enable A/B update process
  • A data partition for storing container runtime data

Partition Layout for QEMU x86-64

The x86_64 image uses GRUB as a bootloader and the partition layout is as follows:

Leda Disk Layout for QEMU x86-64

Partition Layout for QEMU ARM-64

The partition layout for QEMU ARM-based images are comparable, except:

  • Bootloader is replaced with U-Boot

Partition Layout for Raspberry Pi

The partition layout for Raspberry Pi images are comparable, except:

  • Bootloader is replaced with U-Boot
  • The last partition (the data partition) is marked as growable, to allow the use of the larger SD-Card capacities for container runtime data
