Yes, but they would contain almost the same lines, right?  To what
extent is zsh Bourne- or Bash-compatible?  Does ‘export foo=bar’ work
for zsh?

If it does, let’s just keep /etc/profile, and use it for both zsh and
Bash.

It’s OK to have a 2-KiB /etc/zlogin, even when one doesn’t use zsh.

As a first step, what about always installing the skeletons?  Then we
can see whether/how to refine that.
