Unable to bootstrap Guix without substitutes

Unable to bootstrap Guix without substitutes

When installing the Guix binary distribution (both the 1.3.0 release and
most recent guix-binary on ci.guix.gnu.org) on a new system without
enabling substitutes the guix pull or install commands fail when building
bash-mesboot0.
  https://guix.gnu.org/manual/en/html_node/Binary-Installation.html

I see the same failure when building bash-mesboot0 on my working Guix
installation (with substitutes enabled, but disabled for this build):

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix build --no-substitutes -e '(@@ (gnu packages
commencement) bash-mesboot0)'
--8<---------------cut here---------------end--------------->8---

The error from the log:

From the source's bash-2.05b/configure script, the failing section for

The ci builds are marked successful, but the raw log file is either empty
or appears to substitute an earlier build.

I can perform the build successfully using

    $ guix build --check \
        -e '(@@ (gnu packages commencement) bash-masboot0)'

That scary backtrace happens even for the successful build, so I’m
pretty sure it is not the issue.  (Note that the configure test succeeds
in the end with a “yes”.)

Is there anything else suspicious in the logs?

Could it be <https://issues.guix.gnu.org/49985>?

Specifically, the problem occurs when building on NVMe disks.

Timothy,

Thank you for checking this on your own system, it was quite helpful to
know that the failure was not universal.

I found a solution to building bash-mesboot0 in bug #49985 in mounting /tmp
as tmpfs, as noted by Ludo'.

I then saw the error building binutils-mesboot0 as in bug #41264, for which
Mathieu proposed an idea for fixing Mes, still awaiting implementation.

As a temporary fix the same tmpfs trick works when bind mounting /gnu and
/var/guix onto the /tmp tmpfs. This should work for my workflow, and I am
glad to see that others have continued to attempt to bootstrap from source
without substitutes.

I believe this is also the same issue with a broken build as #50203.
