@ -2096,6 +2096,19 @@ want to avoid auto-loading the Emacs packages installed with Guix, you
can do so by running Emacs with the @option{--no-site-file} option
(@pxref{Init File,,, emacs, The GNU Emacs Manual}).
@quotation Note
Emacs can now compile packages natively. Under the default
configuration, this means that Emacs packages will now be
just-in-time (JIT) compiled as you use them, and the results
stored in a subdirectory of your @code{user-emacs-directory}.
Furthermore, the build system for Emacs packages transparently
supports native compilation, but note, that
@code{emacs-minimal}---the default Emacs for building
packages---has been configured without native compilation.
To natively compile your emacs packages ahead of time, use a
transformation like @option{--with-input=emacs-minimal=emacs}.
