I downloaded the latests System Distribution image at
https://alpha.gnu.org/gnu/guix/guixsd-usb-install-0.13.0.x86_64-linux.xz .
I just checked the signature, and it is in order.

This directory in my image is empty.

This directory contains 411 symlinks to binaries, none of which match
with ssh*.

Possibly, Wayne and I used the (experimental) GuixSD 0.13.0 image,
whereas you use the GuixSD 0.13.0 Virtual Machine Image.  I presume we
all are on amd64.

I did find the programs at the locations (with different hash in path)
that Wayne suggested; this issue could be solved by updating the manual
(updating the image can wait until the next release).

That's a useful tip for when I have a similar problem again.  Doing the
installation again results in a succesful installation (well, more or
less).  It is very likely that I forget

    herd start cow-store /mnt

which makes the installation use the harddisk instead of RAM.  However,
I always need to use --fallback.

In any case, thanks to you and Wayne for the useful tips.


Now for the "well, more or less".  When booting my system with a
freshly installed GuixSD, I get this output:

```
waiting for partition 'my-root' to appear...
waiting for partition 'my-root' to appear...
...
ERROR: In procedure scm-error:
ERROR: failed to resolve partition "my-root"
```

My etc/config.scm is here: http://paste.lisp.org/display/360070
