No, indeed.

As discussed on IRC, there are several issues, such as the choice of the
SSH implementation (lshd uses ‘lsh-authorize’ to add authorized keys,
not ~/.ssh/authorized_keys.)  That complicates things.

However, as David suggests, we could have a per-account list of files to
install.  I can imagine something like:

  (user-account
    (name "joe")
    ;; ...
    (files `((".ssh/authorized_keys" ,(local-file "my-authorized-keys"))
             (".emacs.d/foo.el" ,(local-file "foo.el")))))

Now, how should that be handled upon ‘reconfigure’?  By just overriding
those files?  Probably, I guess.

Also, should they be symlinks to the store or copies?
