But you need to do this again whenever Emacs is rebuilt, not just at
bootstrap time.  Right?  Are you relying on the fact that on Posix
hosts bootstrap-emacs and emacs are (currently) the same executable,
and that bootstrap-emacs is generated even when no bootstrap is
necessary, like when building a released tarball?

So you just need _any_ emacs executable capable of code that generates
leim-list.el, is that right?

Well, the actual intent of my question was to see if we need to
discuss the design of this some more ;-)

Thanks.
