Hi,

In case someone reads and is interested by the fix.

Ludo explained the issue on IRC [1].  Well, I should have done
"./pre-inst-env guix pull" with a misconfiguration from source.

Therefore, to fix I did:

  ./configure --localstatedir=/var/ --sysconfigdir=/etc
  make
  ./pre-env-inst guix pull

and everything works fine. :-)


The tarballs are not the same:

A$ md5sum /gnu/store/nkvlqwzvxdlhzlc7vhfcngxc19x2ay2f-docker-pack.tar.gz
b5fe393d7966cbc3cd0be6e51d3aedc3
/gnu/store/nkvlqwzvxdlhzlc7vhfcngxc19x2ay2f-docker-pack.tar.gz

B$ md5sum /gnu/store/nkvlqwzvxdlhzlc7vhfcngxc19x2ay2f-docker-pack.tar.gz
e47b9a38b7162f7fb093b97e19dbc1ca
/gnu/store/nkvlqwzvxdlhzlc7vhfcngxc19x2ay2f-docker-pack.tar.gz

but it is another story, I guess.  Investigating...
