Thanks, but I'd rather not confuse users with Lisp, and neither would
I assume that the first directory in the wildcard expansion will
necessarily be the one belonging to the running Emacs.

What exactly is wrong with the text as written?  It explains where did
27.1 came from:

  Once you have installed the source package, for example at
  /home/myself/deb-src/emacs-27.1, add the following line to your
  startup file:        ^^^^^^^^^^

If you think 27.1 is too old, we could change that to 30 or something.
But other than that, I think the text is fine as it is.

There's only one Emacs package in Fedora as well as in (open)SUSE
the source expanded in that wildcard is to 99% the one that the user
runs, especially for user that would be confused with lisp.

I don't have a problem with 27.1 I just thought there would be a more
streamlined way of setting the patch to the C source code rather than
one that the user to update to each time they update.

I agree with Eli that the current text is fine, and I see that another
patch was installed here.  So I'm closing this bug report now.
