Would this be a good fix:

diff --git a/doc/guix.texi b/doc/guix.texi
index 24db16761..35221ff94 100644
--- a/doc/guix.texi
+++ b/doc/guix.texi
@@ -1572,7 +1572,7 @@ To be able to use such full names for the TrueType fonts 
installed in
 your Guix profile, you need to extend the font path of the X server:
 
 @example
-xset +fp ~/.guix-profile/share/fonts/truetype
+xset +fp `readlink -f ~/.guix-profile/share/fonts/truetype`
 @end example
 
 @cindex @code{xlsfonts}

?

Thanks,
Ludo’.
