# Builds a flashable postmarketOS image for the Fairphone 6 (kernel from
# milos-linux combined-stable + imsd) and publishes it as the rolling
# 'latest' release.
#
# Runs on the dedicated privileged runner label "pmos" (loop devices for
# pmbootstrap install, qemu-user binfmt on the host for the aarch64 chroots).
# Until that runner is registered, dispatched runs will sit queued.
