DISTRO = ${DISTRO}
You can now run 'bitbake <target>'
Some common targets are:
lmp-mini-image - minimal OSTree + OTA capable image
lmp-base-console-image - mini-image + Docker container runtime
lmp-gateway-image - base-console-image + edge gateway related utilities
lmp-factory-image - default (and only available) at FoundriesFactory
