Dockerfile.upgrade-source

# Build an image suitable for upgrade testing: takes the published base image
# and adds the minimal dependencies needed by tmt (rsync, nu, etc.)
# so we can boot it in a VM, then upgrade into the locally-built image.
#
# Note: we do NOT pass `cloudinit` to provision-derived.sh because bcvk
# handles SSH key injection itself; cloud-init interferes with that.
