I have tested your suggestion, disabling the ALTERNATIVE_PRIORITY
declaration:
VIRTUAL-RUNTIME_base-utils = ""
# ALTERNATIVE_PRIORITY =
And effectively the generated image contains any reference to busybox
toolbox at all. Thank you very much for the clarification, Mr Paul!! :-)
I want to add that, if your custom image installs packagegroup-core-boot,
then you also need to set VIRTUAL-RUNTIME_login_manager variable with a
valid value different from "busybox". My custom image includes that
packagegroup, so to achieve my goal, I define in my distro.conf this
variable:
VIRTUAL-RUNTIME_login_manager = "shadow"
Hope this helps to somebody else.
Thank you for all your support! :-)
