Hi,

> If the ENV environment variable exists (exported by /etc/profile or
> ~/.profile) and references an existing file, then all interactive shells
> (login or non-login) will read that file as well.

> This sets the ENV environment variable in /etc/profile, pointing to
> /etc/shinit.
> 
> This also adds /etc/shinit, which:
> 
> * Contains alias and function definitions originally in /etc/profile
> 
> * Sources /etc/mkshrc if the user is using mksh (also originally in
>   /etc/profile), as /etc/mkshrc is meant for all interactive shells
> 
> * Sources ~/.mkshrc if the user is using mksh, to compensate for the
>   fact that mksh will not read ~/.mkshrc if ENV is set
> 
> * Sources ~/.shinit if the user is not using mksh
> 
> This also removes the shebang from /etc/profile, as the file is sourced,
> not executed.

FYI seems like this didnt played well with bash[1].
