To provide more context, these are the ALTERNATIVE variables in the recipe around ALTERNATIVE_LINK_NAME[sh]

ALTERNATIVE:${PN} = "bash sh"

ALTERNATIVE_LINK_NAME[bash] = "${base_bindir}/bash"

ALTERNATIVE_TARGET[bash] = "${base_bindir}/bash"

ALTERNATIVE_LINK_NAME[sh] = "${base_bindir}/sh"

ALTERNATIVE_TARGET[sh] = "${base_bindir}/bash.${BPN}"

Based on earlier messages on ALTERNATIVE_LINK_NAME and ALTERNATIVE_TARGET, I have arrived at the conclusion that a link should be created but isn't.

Thanks,
Devendra
