Changed hook var names to not conflict when used with deploy role

[mlvnds]

When the same vars file is shared across ansistrano deploy and rollback roles, custom task files variables conflict. This comportment force Ansible to only use value of te last declaration of custom task file.

Mmm you are right... I guess most people define these in the playbook itself and not using group_vars or a common vars file.

It can be sorted out with 2 vars files of course but it is not ideal. Not great to break BC for everyone either :)

Can you please rebase latest changes while we consider this?

[ricardclau]

You should keep the include_tasks syntax instead of the old include one

[ricardclau]

Thanks for this contribution! Will add a validation step so that it fails with the old syntax and release a 3.0 version

[ricardclau]

Oh no, I cannot make a fail message as it will fail in your case... well will add some big notes in the readme and release notes
