LGTM.

This only implement part of the #225 story.

For bash, we're relying of the host (ubuntu, fedora, etc.) /etc/profile file, and hope that it'll load all the /etc/profile.d scripts. Seems like an appropriate expectation to have, that being said, maybe at some point we'd like to take full control of /etc/profile. I'm not sure.

As for zsh, it stays un-covered for now.

That being said, a partial solution is preferable to no solution at all.

Let's merge this as it is.
