Hi,

On an i686 computer[1], I've a Guix installation on an HDD, and if I do
> guix pull -M 1 -c 1
and that I then do
> sudo -E guix system reconfigure -M 1 -c 1 system.scm

I get the following boot failure[2]:
> GC Warning: pthread_getattr_np or pthread_attr_getstack failed for
> main thread GC Warning: Couldn't read /proc/stat
> Welcome, this is GNU's early boot Guile.

If I use the same system.scm (attached) and that I produce an image
with the build_init.sh script (attached) which setups an encrypted
partition and uses guix system init, and that I then copy the resulting
image to an USB drive with ddrescue, It then boots fine.

Since the system ends up not booting anymore when I try to guix pull
and guix system reconfigure the system on the HDD, to boot I simply
select a known booting old revision in the grub menu, so I can easily
test things.

Though I'm not sure where to look. Is there anything I can do to get
more contexts or logs? Should I try loglevel=8 ?

That sounds weird, I would expect our guile to be more recent than that. The manual suggests using "sudo guix system" instead of "sudo -E guix system", maybe that's the issue?
