/etc/environment is defined by pam_env to be a simple KEY=VAL file, with no
support for varibales substitute. If we do not use pam_env (linux specified?),
I think we should let /etc/zlogin source /etc/profile instead.
And we don't want /etc/zlogin when not using zsh at all,
IIUC while skeletons is configurable at the top os-expr, /etc/zlogin is
not.

It seem too much, what I suggested is:
for login, su (pam_env): /etc/environment
for login shell: ~/.bash_profile, ~/.zlogin
for interactive: ~/.bashrc, ~/.zshrc
skeletons only installed when needed :)
