# bcvk development VM management
#
# The dev binary is overlaid onto /usr via systemd-sysext. After
# rebuilding with `just sysext`, run `just bcvk sync` to
# refresh the overlay (~30s total cycle).
#
# Usage:
#   just bcvk up            # Build sysext + launch persistent VM
#   just bcvk sync          # Rebuild sysext + refresh overlay (~30s)
#   just bcvk ssh           # SSH into the VM
#   just bcvk ephemeral     # Ephemeral VM (full image, destroyed on exit)
