It checked whether busybox is in task-depends.dot after run "bitbake -g
core-image-minimal", but busybox is not a must for core-image-minimal since it
is configurable:
VIRTUAL-RUNTIME_base-utils = ""
VIRTUAL-RUNTIME_base-utils-syslog = ""
VIRTUAL-RUNTIME_base-utils-hwclock = ""
VIRTUAL-RUNTIME_login_manager = "shadow"
VIRTUAL-RUNTIME_syslog = ""
So the case may fail when busybox is not present, check
base-files which is more reliable.
