-------------------------------------

Hi:
I agree with what you said "use dependency cache script file globally to speed 
up the startup again".  If you are interested, you are welcome to mention a 
Pull Request about this.
However, it is unnecessary to turn the dependency cache script file into a 
hidden file, because if some of the user's environmental dependencies change, 
the cache files will out-of-date, and then the user needs to delete these cache 
files. Hiding them is not good for users to find them.

> dependency cache script files not fully used

> kylin startup-related scripts will generate dependent cache scripts at the 
> first startup to speed up the second startup. Now it is found that the 
> dependent cache scripts are not fully utilized. Only some scripts use this 
> file. It is recommended to use this file globally to speed up the startup 
> again, and it is recommended that the generated cache file start with ".", so 
> that dependent cache scripts are not directly visible
