Hi,
Can explain in little detail, on how to create and use runtime package.
Do I need to create a noux package?
One first step could be copying the system-shell's 'pkg' and 'raw' recipes and to exchange each 'coreutils-minimal' occurrence with 'coreutils'.
I carry around my own personal shell pkg [1] and if you compare both you will spot the differences that might help you to create your own customized version.
