Dockerfile starter for WINE + VNC that works with Apple Silicon

	# The apt repositories for ARM and Intel/AMD are hosted on different servers
	# (ports.ubuntu.com vs archive.ubuntu.com), which requires some finagling to get
	# apt's sources correct so we can install i386 packages regardless of our native
	# platform.
	#
	# There are no official i386 containers for Ubuntu 20.04 "Focal" and newer, so
	# we assume that we can use the amd64

rgov / kernel-uimage+dtb.bbclass

Created January 17, 2022 21:20

	# As of Linux version 3.7, we must provide a device tree blob on boot so that
	# the kernel understands our hardware configuration.
	#
	# However, the version of U-Boot currently in use predates the use of device
	# trees, and provides no way of specifying the DTB to load. Therefore, there
	# exists a configuration option CONFIG_ARM_APPENDED_DTB=y which instructs the
	# kernel to find the DTB immediate following the kernel image itself.
	#
	# To produce a uImage file with the combined kernel + DTB, we just concatenate
	# the two before running mkimage. (Note, the uImage file header includes a
