Yeah, I wanted to send you a heads-up and then I forgot, apologies!

In general, my suggestion when fiddling with these things is to at least
run:

  make check-system TESTS=basic

This one builds and runs quickly and catches the most obvious issues, as
in this case.

Then, when fiddling with the bootloader, file systems, and that kind of
stuff, it’s a good idea to run an installation test, as in:

  make check-system TESTS=installed-os

This is more expensive to build (it first has to build ‘guix’, then an
ISO image, and then run the installation), but it’s a good idea when
low-level things are modified.  See:

  https://guix.gnu.org/manual/en/html_node/Running-the-Test-Suite.html

I’m not sure I understand what this change meant to fix though.  What
was the initial problem that led to the addition of this
‘canonicalize-path’ call?

Thanks,
Ludo’.
