bug#36724: Unable to independently verify the new bootstrap binaries

[Mark H Weaver]

Hi,

I'd like to start compiling 'core-updates' on my machine, but first I
wish to independently verify the new bootstrap binaries.  I'm running
into difficulties with that.

I started by building the new bootstrap binaries from commit
4ae7dc7b9af64794081b1913740b97acd89c91bc, as cited in this commit:

commit da3c6a7f19ef1243af725f63c16c8fd92fde33b4
Author: Jan Nieuwenhuizen <janneke@gnu.org>
Date:   Sat Nov 24 08:49:21 2018 +0100

    bootstrap: Switch to official bootstrap urls.
    
    Built with
    
        4ae7dc7b9af64794081b1913740b97acd89c91bc
        gnu: Remove duplicate linux-libre-headers package from bootstrap inputs.
    
    * gnu/packages/bootstrap.scm (%bootstrap-linux-libre-headers): Switch to
    official bootstrap urls.
    (%bootstrap-mescc-tools): Likewise.
    (%bootstrap-mes): Likewise.
--8<---------------cut here---------------end--------------->8---

However, this produces 'mes-minimal-stripped-0.18-0.08f04f5' (etc),
whereas the current bootstrap binaries include
'mes-minimal-stripped-0.19'.  My goal now is to independently build
this.

I searched for the commit that updated to 0.19, and found this:

    bootstrap: bootstrap-mes: Update.
    
    Built with
    
        ef809e3ac036eccc5f9c9edd8fb661d14ae15f2f
        bootstrap: Add mes-boot0; decouple mes-boot from Mes.
    
    * gnu/packages/bootstrap.scm (%bootstrap-mes): Update.
--8<---------------cut here---------------end--------------->8---

So, I then ran "./pre-inst-env guix build bootstrap-tarballs
--system=i686-linux" from a git checkout at commit
ef809e3ac036eccc5f9c9edd8fb661d14ae15f2f.

On my X200, that leads to an error while building glibc-mesboot-2.16.0:

I'm unsure how to proceed.  Can someone please help me independently
verify these binaries?

Good that you are verifying this.  IIRC, Ludo' has verified all
bootstrap binaries that I built before we dared to trust them...but
maybe that's a bit thin?

Yeah, that should do it.

Oh my, that's interesting.  You can imagine that I saw many similar
errors while developing this whole bootstrap chain.

I tried to rebuild the bootstrap binaries without using substitutes on
our small build farm, which succeeded.  Then I tried building
glibc-mesboot just now on my laptop and much to my relief I had no
problem, which makes it even more interesting.

Here's what I just did

Yeah, I don't know...Do I dare to suggest you give it a retry?  I built
it on a x86_64 dell xps-13 9350.  Your X200 is also 64bits right?

bug#36724: Unable to independently verify the new bootstrap binaries

[Mark H Weaver]

Hi Janneke,

It built successfully on the second attempt.  I'm curious what happened,
but not quite curious enough to investigate further.  Too much else to
do.  I'll close this bug for now.

      Thanks!
        Mark
