Hi again,

I’m sure I’m doing something wrong (see below for guesses).  Here’s what
I get:

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix pull

I modified build-self.scm to use the modified Guile:

                          (else

--8<---------------cut here---------------end--------------->8---

I also confirmed that the Guile process that is spawned as “bin/guile
--no-auto-compile /home/rwurmus/guix/scripts/guix pull” is indeed the
modified Guile, but I noticed that it spawns yet another Guile process
to load and compile Guix.

I guess that comes from the daemon?  If that’s the case I can’t really
test this on this big server, because the daemon is currently in use, so
I can’t just reconfigure it to use the modified Guile.

When compiling Guix from source with “make -j 32” using that version of
Guile I got a segfault.
