Roberto, may I share a joke, to do not be a monolog?
#joke: a poor man walking, but he needs a bicycle (more comfort) [1]. So, he will borrow some resources [2] to build a factory [3] which will produce many (motor)bicycles, but he only needs one bicycle for him.
Legend:
[1] = novice/lethargic Linux user, wanting a custom Tiny core.
[2] = time spent to understand your scripts (not blindly run them); plus compile some programs, knowledge about git, etc.
[3] = need for a full OS (Ubuntu?) + tools, a new shell (bash, not ash), etc.
PS: for me, it is like the “Mexican Fisherman and the Investment Banker” parable. YMMV.
