Good catch.  I believe this is fixed by commit a52127c.

Can you confirm that it works for you?

Thanks,

The var/guix directory gets installed according to the configuration of
the host Guix, instead of the installed Guix (that is, /var).

This means that if someone (like me) configured the host Guix with
--prefix=/usr/local, the directory will be installed
into /usr/local/var/guix, which won't work, and will cause the installed
guix to see an empty /gnu/store.

This is dangerous because then, it will try to download glibc, and while
doing that, it will delete the existing one in /gnu/store, and kill the
operating system.

Workarounds:
1. Configure the host guix with --prefix=/
or
2. Once the system is initialized, move the var/guix folder (eg,
from /usr/local/var) to /var
