Hi Ludo,
What does “uname -r” report on your system?
4.4.0-78-generic
It's an up-to-date Ubuntu 16.04 installation.
(This functionality is used only by the container facilities of ‘guix environment’ and ‘guix system’, so you shouldn’t take it as a blocker.)
OK, then I will just go ahead and switch to "guix from git". Thanks, Konrad.
