If there _is_ no normal zshrc, zsh-newuser-install will run. As we can
easily replace this function, ZSH does the handling of this for free.
The default zsh could be loaded the second a user presses enter on
the little welcome screen menu grml displays on tty1 and everything
set up to use this config, as well. Said menu would run from
zsh-newuser-install then, btw.

As I autoload every one of my functions in my zshrc via globbing, I
would want to keep softlinks for the functions moved into main,
but yes, that is a good idea.

[[ -n $ZSHRC_ALT ]] && . /etc/zsh/rcs/$ZSHRC_ALT.d

in all zshrcs would mean you can fork and otherwise mangle them
without needing to touch anything in the actual file.

This should exist and overwrite the normal zsh-newuser-install.

I would rather have a ~/.zshrc that simply uses $ZDOTDIR to
source everything. Solves two problems in one go.

Would also be solved by the above, so make that three.
