 * Emacs archives

+configuration.
+
+Hence I've introduced this measure: a compressed archive of a minimal
+viable configuration for Emacs.  This contains my configuration files,
+custom Lisp code, all the repositories for external packages I use and
+the straight package cache.  Instead of downloading each repository
+individually, this archive contains all of them immediately.
+
+On my current machine after downloading the archive it takes around
+209s to completely build the system including both package and custom
+Lisp compilation.  Once this is done Emacs takes less than 1 second to
+boot.
+
+*NOTE*: This time doesn't include the native compilation time, as that
+ is asynchronous anyway.
+** Scripts
+*IMPORTANT*: These are heavy scripts, expect them to take a while.
+Therefore, if in Emacs, do _not_ run these via ~C-c C-c~ because it
+will block the main thread.
 
 This script generates the archive:
 #+begin_src sh
-tar -Jcvf emacs-config.tar.xz \
+tar --use-compress-program="zstdmt -19 -T0" \
+    -cvf emacs-config.tar.zst \
     ~/.config/emacs/config.org \
     ~/.config/emacs/early-init.el \
     ~/.config/emacs/init.el \
     ~/.config/emacs/elisp/ \
-    ~/.config/emacs/straight/
+    ~/.config/emacs/.config/custom.el \
+    ~/.config/emacs/straight/versions/default.el \

 And this script sends it over via rsync

-* Installing Emacs
-I like a specific set of flags on my Emacs install, and my
-configuration kind of depends on them existing as well.  Prepackaged
-installs just won't cut it.  So I'd highly recommend cloning and
-building my personal
-[[https://github.com/oreodave/emacs-29-custom][Emacs repo]] (currently
-=v29=).
-
-Or just run the following lines:
-
-#+begin_src sh
-cd ~/.local/src;
-git clone git@github.com:oreodave/emacs-29-custom emacs;
-cd emacs;
-sh personal-install; # Will configure, build and attempt to install
-#+end_src
