bug#70140: Missing ./doc/guix-cookbook.pt_BR.texi

[pelzflorian (Florian Pelz)]

Hello Rostislav.

I do not know how to address the issue properly or where to document it.
The Writing Documentation section is the wrong place, because everyone
has to bootstrap again, not only the one who is writing documentation;
if we put a notice somewhere, then it would be something like:

diff --git a/doc/contributing.texi b/doc/contributing.texi
index f5b01f42fd..2dd4be951f 100644
--- a/doc/contributing.texi
+++ b/doc/contributing.texi

with an error
 similar to the following example:
 
 @example
 error: failed to load 'gnu/packages/linux.scm':
 ice-9/eval.scm:293:34: In procedure abi-check: #<record-type <origin>>: record 
ABI mismatch; recompilation needed
 @end example
 
 This means that one of the record types that Guix defines (in this
 example, the @code{origin} record) has changed, and all of guix needs
 to be recompiled to take that change into account.  To do so, run
 @command{make clean-go} followed by @command{make}.
 
+If after updating, @command{make} fails with another error message,
+you probably have to repeat all steps described here, starting with
+@command{./bootstrap}.

 In order to keep a sane working environment, you will find it useful to
 test the changes made in your local source tree checkout without
 actually installing them.  So that you can distinguish between your
 ``end-user'' hat and your ``motley'' costume.
 
 To that end, all the command-line tools can be used even if you have not
 run @code{make install}.  To do that, you first need to have an
 environment with all the dependencies available (@pxref{Building from
 Git}), and then simply prefix each command with @command{./pre-inst-env}

Would that be OK?
