v0.0.5 — automated migration from a memory card to an SSD

Highlights

  • A guided operation to move a Raspberry Pi 5’s system from its memory card to an SSD, offered only when the node actually qualifies — the right board, an SSD attached and sized correctly, and compatible firmware — and refused with the specific reason otherwise.
  • The rest of the SSD becomes usable storage capacity as part of the same operation, reserved before anything is copied so it can’t be silently absorbed later.
  • The memory card is never touched destructively until you explicitly confirm removing it at the end. If the migration is aborted or fails partway through, the node simply keeps working from the memory card as before.

Known limitations

  • Only a Raspberry Pi 5 with a compatible SSD expansion board is supported. Other boards and drive layouts are refused by the eligibility check, not attempted.
  • No whole-disk cloning, no migrating onto a memory card, and no migrating between two SSDs.
  • Buddy detects out-of-date firmware and offers the existing update action, but never updates it on its own without you choosing to.
