> merged /usr
>
> Prepare the symlinks required for merged /usr at the time of rootfs
> creation.
>
> The links created in rootfs are:
> /bin --> /usr/sbin
> /sbin --> /usr/sbin
> /lib --> /usr/lib
> /lib64 --> /usr/lib64
>
> We cannot make these symlinks as part of 'base-files' or some other
> package.
> Because at rootfs creation, installation of the package(say kernel)
> that depends
> on these root folders/links fails, if package manager installs this
> package
> prior to base-files.
>
> These symbolic links in top level folder should be present as long as
> - kernel tools use /lib/{module,firmware}
> - shell scripts uses "#!/bin/sh"

You missed one. Change "/${baselib}" to "${baselib}".
