	# Why are we doing this?
	#
	# The hosted GitHub runners have free disk space split
	# between the root partition and a temporary partition,
	# leaving limited space for builds. We work around this
	# with easimon/maximize-build-space which creates a LVM
	# volume to combine the free space in both.
	#
	# We mount this new volume at /nix, and set TMPDIR so
	# all builds happen inside the volume.
