There is one use case.below.
So I have role base which is base of every other role. In that the defaul/main.yml I defined a users dict like:
users:
jumbo:
name: "jumbo"
sshcopykey: 'string'
The code of generate user etc is in role base.
I want in the sub role if it wants to overrides the users to generate freely. So
If the sshcopykey is a file path or template path it is not work unless I have to add these templates / file into role base folder structure (the files/ or templates/ ) If I added in subrole it does not work as code to implement it in role base it does not search for the sub role template path.
So I do not want to put in role base because it is technically not belong to role base at all.
If I changes to use the content in copy I can achieve that cleanly. At least for now.
Thanks
