+The next step that Guix has taken towards a Full Source Bootstrap is to
+replace the shell and all its utilities with implementations in Guile
+Scheme.  Gash (@pxref{Gash,,, gash, The Gash manual}) is a
+POSIX-compatible shell that replaces Bash, and it comes with Gash Utils
+which has minimalist replacements for Awk, the GNU Core Utilities, Grep,
+Gzip, Sed, and Tar.  The rest of the bootstrap binary seeds that were
+removed are now built from source by adding a new set of
+@c

+As Gash and Gash Utils mature, and GNU packages become more
+bootstrappable (e.g., new releases of GNU Sed will also ship in
+@code{tar.gz} format), this set of added packages can hopefully be
+reduced again.
