Some year after the question on alipline 3.17 I figured out a solution (may not be the best, any comment welcome).

* Edit as root `/etc/profile` to add at the end just before the `unset script` this line:
 ```lang-shell
 . $HOME/.profile
 ```
* Then create a `.profile` in your home dir as described before like this:
 ```lang-shell
 ENV=$HOME/.ashrc; export ENV
 . $ENV
 ```

Then you can create a `.ashrc` in your home dir to set you aliases or other stuff.
